https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

libImaging/TgaRleDecode.c in Pillow 9.1.0 has a heap buffer overflow in the processing of invalid TGA image files.

Pillow 10.0.1 updates its C dependency 'libwebp' to 1.3.2 to include a fix for a high-risk vulnerability.
https://pillow.readthedocs.io/en/stable/releasenotes/10.0.1.html

Pillow is affected by an arbitrary code execution vulnerability. If an attacker has control over the keys passed to the environment argument of PIL.ImageMath.eval(), they may be able to execute arbitrary code.
https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Awscli 1.27.90 includes a fix for a potential low-serverity ReDoS vulnerability: An attacker being able to craft a malicious nuget.config file can cause ReDoS, when a user performs Nuget or Dotnet login.
https://github.com/aws/aws-cli/commit/68ad24c36b4e3f6936e3d1dc76fda39d2d1fe764

Affected versions of the awscli package are vulnerable to Information Disclosure due to incorrect default file permissions when creating the cli_history SQLite database on Unix systems. When cli_history is enabled, awscli writes command history (including command parameters and stored API request/response data) to a local SQLite history database file, which may be created with permissions that allow other local users to read it.

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.
https://github.com/squidfunk/mkdocs-material/commit/fe11bc0cabd692d37bc4cc4e8034dbe6783ef36b

MKDocs Material addresses an RXSS vulnerability found in deep links within search results.

Mkdocs-material 9.1.13 includes a fix for a Race Condition Vulnerability. Social plugin triggers the race condition vulnerability when downloading fonts.

Affected versions of the package djangorestframework are vulnerable to Cross-site Scripting (XSS) via the break_long_headers template filter due to improper input sanitization before splitting and joining with <br> tags.

Tqdm version 4.66.3 addresses CVE-2024-34062, a vulnerability where optional non-boolean CLI arguments like `--delim`, `--buf-size`, and `--manpath` were passed through Python's `eval`, allowing for arbitrary code execution. This security risk, only locally exploitable, has been mitigated in this release. Users are advised to upgrade to version 4.66.3 immediately as there are no workarounds for this issue.

Mkdocs 1.3.0 fixes an XSS vulnerability which was present when using the search function in built-in themes.

However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory.

https://github.com/aws/aws-cli/commit/68ad24c36b4e3f6936e3d1dc76fda39d2d1fe764

Affected versions of the awscli package are vulnerable to Information Disclosure due to incorrect default file permissions when creating the cli_history SQLite database on Unix systems. When cli_history is enabled, awscli writes command history (including command parameters and stored API request/response data) to a local SQLite history database file, which may be created with permissions that allow other local users to read it.

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Affected versions of the package djangorestframework are vulnerable to Cross-site Scripting (XSS) via the break_long_headers template filter due to improper input sanitization before splitting and joining with <br> tags.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function.

The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

libImaging/TgaRleDecode.c in Pillow 9.1.0 has a heap buffer overflow in the processing of invalid TGA image files.

Pillow 10.0.1 updates its C dependency 'libwebp' to 1.3.2 to include a fix for a high-risk vulnerability.
https://pillow.readthedocs.io/en/stable/releasenotes/10.0.1.html

Pillow is affected by an arbitrary code execution vulnerability. If an attacker has control over the keys passed to the environment argument of PIL.ImageMath.eval(), they may be able to execute arbitrary code.
https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Awscli 1.27.90 includes a fix for a potential low-serverity ReDoS vulnerability: An attacker being able to craft a malicious nuget.config file can cause ReDoS, when a user performs Nuget or Dotnet login.
https://github.com/aws/aws-cli/commit/68ad24c36b4e3f6936e3d1dc76fda39d2d1fe764

Affected versions of the awscli package are vulnerable to Information Disclosure due to incorrect default file permissions when creating the cli_history SQLite database on Unix systems. When cli_history is enabled, awscli writes command history (including command parameters and stored API request/response data) to a local SQLite history database file, which may be created with permissions that allow other local users to read it.

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.
https://pyup.io/posts/pyup-discovers-redos-vulnerabilities-in-top-python-packages-part-2

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Affected versions of the package djangorestframework are vulnerable to Cross-site Scripting (XSS) via the break_long_headers template filter due to improper input sanitization before splitting and joining with <br> tags.

Tqdm version 4.66.3 addresses CVE-2024-34062, a vulnerability where optional non-boolean CLI arguments like `--delim`, `--buf-size`, and `--manpath` were passed through Python's `eval`, allowing for arbitrary code execution. This security risk, only locally exploitable, has been mitigated in this release. Users are advised to upgrade to version 4.66.3 immediately as there are no workarounds for this issue.

Mkdocs 1.3.0 fixes an XSS vulnerability which was present when using the search function in built-in themes.
https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

libImaging/TgaRleDecode.c in Pillow 9.1.0 has a heap buffer overflow in the processing of invalid TGA image files.

Pillow 10.0.1 updates its C dependency 'libwebp' to 1.3.2 to include a fix for a high-risk vulnerability.
https://pillow.readthedocs.io/en/stable/releasenotes/10.0.1.html

Pillow is affected by an arbitrary code execution vulnerability. If an attacker has control over the keys passed to the environment argument of PIL.ImageMath.eval(), they may be able to execute arbitrary code.
https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.
https://github.com/squidfunk/mkdocs-material/commit/fe11bc0cabd692d37bc4cc4e8034dbe6783ef36b

Tqdm version 4.66.3 addresses CVE-2024-34062, a vulnerability where optional non-boolean CLI arguments like `--delim`, `--buf-size`, and `--manpath` were passed through Python's `eval`, allowing for arbitrary code execution. This security risk, only locally exploitable, has been mitigated in this release. Users are advised to upgrade to version 4.66.3 immediately as there are no workarounds for this issue.

Mkdocs 1.3.0 fixes an XSS vulnerability which was present when using the search function in built-in themes.
https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

Pillow 10.0.1 updates its C dependency 'libwebp' to 1.3.2 to include a fix for a high-risk vulnerability.
https://pillow.readthedocs.io/en/stable/releasenotes/10.0.1.html

Pillow is affected by an arbitrary code execution vulnerability. If an attacker has control over the keys passed to the environment argument of PIL.ImageMath.eval(), they may be able to execute arbitrary code.
https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Awscli 1.27.90 includes a fix for a potential low-serverity ReDoS vulnerability: An attacker being able to craft a malicious nuget.config file can cause ReDoS, when a user performs Nuget or Dotnet login.
https://github.com/aws/aws-cli/commit/68ad24c36b4e3f6936e3d1dc76fda39d2d1fe764

Affected versions of the awscli package are vulnerable to Information Disclosure due to incorrect default file permissions when creating the cli_history SQLite database on Unix systems. When cli_history is enabled, awscli writes command history (including command parameters and stored API request/response data) to a local SQLite history database file, which may be created with permissions that allow other local users to read it.

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.
https://github.com/squidfunk/mkdocs-material/commit/fe11bc0cabd692d37bc4cc4e8034dbe6783ef36b

Affected versions of the package djangorestframework are vulnerable to Cross-site Scripting (XSS) via the break_long_headers template filter due to improper input sanitization before splitting and joining with <br> tags.

Tqdm version 4.66.3 addresses CVE-2024-34062, a vulnerability where optional non-boolean CLI arguments like `--delim`, `--buf-size`, and `--manpath` were passed through Python's `eval`, allowing for arbitrary code execution. This security risk, only locally exploitable, has been mitigated in this release. Users are advised to upgrade to version 4.66.3 immediately as there are no workarounds for this issue.

Mkdocs 1.3.0 fixes an XSS vulnerability which was present when using the search function in built-in themes.
https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

libImaging/TgaRleDecode.c in Pillow 9.1.0 has a heap buffer overflow in the processing of invalid TGA image files.

Pillow 10.0.1 updates its C dependency 'libwebp' to 1.3.2 to include a fix for a high-risk vulnerability.
https://pillow.readthedocs.io/en/stable/releasenotes/10.0.1.html

Pillow is affected by an arbitrary code execution vulnerability. If an attacker has control over the keys passed to the environment argument of PIL.ImageMath.eval(), they may be able to execute arbitrary code.
https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Awscli 1.27.90 includes a fix for a potential low-serverity ReDoS vulnerability: An attacker being able to craft a malicious nuget.config file can cause ReDoS, when a user performs Nuget or Dotnet login.
https://github.com/aws/aws-cli/commit/68ad24c36b4e3f6936e3d1dc76fda39d2d1fe764

Affected versions of the awscli package are vulnerable to Information Disclosure due to incorrect default file permissions when creating the cli_history SQLite database on Unix systems. When cli_history is enabled, awscli writes command history (including command parameters and stored API request/response data) to a local SQLite history database file, which may be created with permissions that allow other local users to read it.

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.
https://pyup.io/posts/pyup-discovers-redos-vulnerabilities-in-top-python-packages-part-2

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.
https://github.com/squidfunk/mkdocs-material/commit/fe11bc0cabd692d37bc4cc4e8034dbe6783ef36b

MKDocs Material addresses an RXSS vulnerability found in deep links within search results.

Mkdocs-material 9.1.13 includes a fix for a Race Condition Vulnerability. Social plugin triggers the race condition vulnerability when downloading fonts.
https://github.com/squidfunk/mkdocs-material/issues/5515
https://github.com/squidfunk/mkdocs-material/issues/5521

Affected versions of the package djangorestframework are vulnerable to Cross-site Scripting (XSS) via the break_long_headers template filter due to improper input sanitization before splitting and joining with <br> tags.

Tqdm version 4.66.3 addresses CVE-2024-34062, a vulnerability where optional non-boolean CLI arguments like `--delim`, `--buf-size`, and `--manpath` were passed through Python's `eval`, allowing for arbitrary code execution. This security risk, only locally exploitable, has been mitigated in this release. Users are advised to upgrade to version 4.66.3 immediately as there are no workarounds for this issue.

Mkdocs 1.3.0 fixes an XSS vulnerability which was present when using the search function in built-in themes.
https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.

https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save(). This could enable an attacker to manipulate file paths and access unintended directories.

Django addresses a memory exhaustion issue in django.utils.numberformat.floatformat(). When floatformat receives a string representation of a number in scientific notation with a large exponent, it could lead to excessive memory consumption. To prevent this, decimals with more than 200 digits are now returned as-is.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient neutralization of user-controlled column alias names provided via dictionary expansion. The QuerySet.annotate(), QuerySet.alias(), QuerySet.aggregate(), and QuerySet.extra() methods accept **kwargs whose keys are used as column aliases, and on MySQL and MariaDB, those identifiers are not safely quoted, permitting crafted input to be incorporated into the generated SQL.

Affected versions of the Django package are vulnerable to SQL Injection due to insufficient input sanitization in FilteredRelation column aliases. The FilteredRelation class fails to properly validate or escape column alias names when they are provided through dictionary expansion as keyword arguments to QuerySet.annotate() or QuerySet.alias() methods, allowing malicious SQL code to be injected directly into the generated database queries.

CVE-2025-64458: Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to slow Unicode NFKC normalization on Windows being applied to untrusted inputs. The django.contrib.auth.views.LoginView and django.contrib.auth.views.LogoutView, and django.views.i18n.set_language normalize user-controlled strings using Python’s NFKC algorithm, which is unusually slow on Windows for huge Unicode sequences and can be triggered to consume excessive CPU.

Affected versions of the Django package are vulnerable to Denial of Service due to unbounded request-body allocation when reading HttpRequest.body for ASGI requests whose Content-Length header is missing or understates the actual payload size. The body-reading path relies on the declared Content-Length to enforce the DATA_UPLOAD_MAX_MEMORY_SIZE cap, so an ASGI request that omits Content-Length or advertises a smaller value than the payload being streamed bypasses the limit check and reads the full incoming body into memory. An unauthenticated remote attacker can exploit this against a Django application served over ASGI by sending a request without Content-Length or with an understated value, causing the server to load an arbitrarily large request body into memory and exhaust available resources on the host.

Affected versions of the Django package are vulnerable to Missing Authorization due to the admin changelist view processing forged POST data against a ModelAdmin that defines list_editable without enforcing that submitted rows correspond only to existing records a user is permitted to edit. The changelist form handling is under ModelAdmin.list_editable accepts form entries whose primary key values do not match any existing row and creates new instances from them, treating the inline edit endpoint as an implicit create path that bypasses the add-permission check. An authenticated admin user who holds change permission on a model exposed via list_editable but lacks add permission can exploit this by submitting crafted POST data to the changelist endpoint to create new instances of that model, resulting in unauthorized record creation within the Django admin.

Affected versions of Django are vulnerable to a potential denial-of-service (DoS) attack in the `django.utils.html.strip_tags()` method. The vulnerability occurs when the `strip_tags()` method or the `striptags` template filter processes inputs containing large sequences of nested, incomplete HTML entities.

Django affected versions are vulnerable to a potential SQL injection in the HasKey(lhs, rhs) lookup on Oracle databases. The vulnerability arises when untrusted data is directly used as the lhs value in the django.db.models.fields.json.HasKey lookup. However, applications using the jsonfield.has_key lookup with the __ syntax remain unaffected by this issue.

An issue was discovered in Django 5.2 before 5.2.3, 5.1 before 5.1.11, and 4.2 before 4.2.23. Internal HTTP response logging does not escape request.path, which allows remote attackers to potentially manipulate log output via crafted URLs. This may lead to log injection or forgery when logs are viewed in terminals or processed by external systems.

Affected versions of the Django package are vulnerable to HTTP Header Spoofing due to ambiguous normalisation of request header names in ASGIRequest, where two distinct on-the-wire header variants that differ only in underscore versus hyphen separators collapse to the same internal key. When Django builds the request META mapping for an ASGI request, a header such as X-Forwarded-For and a client-supplied X_Forwarded_For are both mapped to the single underscore form, so an attacker-controlled header can overwrite or masquerade as a trusted header set by a fronting proxy or middleware. An unauthenticated remote attacker can exploit this by sending an HTTP request containing an underscore-separated header name that collides with a trusted hyphenated header to spoof values relied on by downstream middleware or application code, such as forwarded-client or authentication-related headers, leading to authentication bypass and integrity impact.

Affected versions of Django are potentially vulnerable to denial-of-service via the get_supported_language_variant() method. This method was susceptible to a denial-of-service attack when used with very long strings containing specific characters. Exploiting this vulnerability could cause significant delays or crashes in the affected application, potentially leading to service disruption.

Affected versions of Django are affected by a username enumeration vulnerability caused by timing differences in the django.contrib.auth.backends.ModelBackend.authenticate() method. This method allowed remote attackers to enumerate users through a timing attack involving login requests for users with unusable passwords. The timing difference in the authentication process exposed whether a username was valid or not, potentially aiding attackers in gaining unauthorized access.

Django has a potential denial-of-service vulnerability in django.utils.html.urlize() and AdminURLFieldWidget. The urlize and urlizetrunc functions, along with AdminURLFieldWidget, are vulnerable to denial-of-service attacks when handling inputs with a very large number of Unicode characters.

CVE-2025-64459: Affected versions of the Django package are vulnerable to SQL Injection due to improper input validation, allowing the internal _connector keyword argument to be accepted from untrusted dictionaries via expansion. The .filter(), .exclude(), and .get() methods on QuerySet, as well as the Q class, resolve **kwargs and will treat a supplied _connector value as the logical connector without constraining it to the expected set (AND/OR), permitting attacker-controlled tokens to influence SQL predicate construction.

Django fixes potential SQL injection in ``FilteredRelation`` column aliases on PostgreSQL.

Affected versions of the pillow package are vulnerable to Integer Overflow due to unchecked accumulation of glyph advance values while tracking the current rendering position during font processing. When a font supplies an excessively large advance for each glyph, the running position counter wraps around because the arithmetic is performed in a fixed-width integer type that cannot represent the resulting magnitude. A remote attacker who can supply a crafted font file to a target that uses Pillow's font rendering can trigger the overflow, leading to incorrect memory calculations and potential memory corruption.

Affected versions of the pillow package are vulnerable to Denial of Service due to an unbounded loop when traversing PDF cross-reference trailer chains without cycle detection. The PdfParser module follows Prev pointers in PDF trailers to read cross-reference sections, but it does not track previously processed offsets, so a trailer whose Prev pointer references its own offset or forms a longer cycle causes the parser to loop indefinitely. A remote attacker who supplies a crafted PDF document can cause the parsing process to hang, consuming 100% CPU and rendering the consuming application unresponsive.

Pillow 10.0.0 includes a fix for CVE-2023-44271: Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
https://github.com/python-pillow/Pillow/pull/7244

Pillow 10.3.0 introduces a security update addressing CVE-2024-28219 by replacing certain functions with strncpy to prevent buffer overflow issues.

libImaging/TgaRleDecode.c in Pillow 9.1.0 has a heap buffer overflow in the processing of invalid TGA image files.

Pillow 10.0.1 updates its C dependency 'libwebp' to 1.3.2 to include a fix for a high-risk vulnerability.
https://pillow.readthedocs.io/en/stable/releasenotes/10.0.1.html

Pillow is affected by an arbitrary code execution vulnerability. If an attacker has control over the keys passed to the environment argument of PIL.ImageMath.eval(), they may be able to execute arbitrary code.
https://pillow.readthedocs.io/en/stable/releasenotes/10.2.0.html

Pillow 9.3.0 includes a security fix: Pillow will now decode the data in its natural CMYK mode, then convert it to RGB and rearrange the channels afterwards. Trying to load the data in an incorrect mode could result in a segmentation fault.
https://pillow.readthedocs.io/en/stable/releasenotes/9.3.0.html#decode-jpeg-compressed-blp1-data-in-original-mode

Pillow is potentially vulnerable to DoS attacks through PIL.ImageFont.ImageFont.getmask(). A decompression bomb check has also been added to the affected function.

Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).

Awscli 1.27.90 includes a fix for a potential low-serverity ReDoS vulnerability: An attacker being able to craft a malicious nuget.config file can cause ReDoS, when a user performs Nuget or Dotnet login.
https://github.com/aws/aws-cli/commit/68ad24c36b4e3f6936e3d1dc76fda39d2d1fe764

Affected versions of the awscli package are vulnerable to Information Disclosure due to incorrect default file permissions when creating the cli_history SQLite database on Unix systems. When cli_history is enabled, awscli writes command history (including command parameters and stored API request/response data) to a local SQLite history database file, which may be created with permissions that allow other local users to read it.

Pygments 2.15.0 includes a fix for CVE-2022-40896: The regular expressions used when parsing Smithy, SQL/SQL+Jinja, and Java properties files were discovered to be vulnerable. As a result, pygmentizing a maliciously-crafted file of these kinds would have resulted in high resources consumption or crashing of the application.

Affected versions of Requests, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. Requests 2.32.0 fixes the issue, but versions 2.32.0 and 2.32.1 were yanked due to conflicts with CVE-2024-35195 mitigation.

Affected versions of the requests package are vulnerable to Insecure Temporary File reuse due to predictable temporary filename generation in extract_zipped_paths(). The requests.utils.extract_zipped_paths() utility extracts files from zip archives into the system temporary directory using a deterministic path, and if that file already exists, the function reuses it without validating that it is the expected extracted content.

Requests is an HTTP library. Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs. Users should upgrade to version 2.32.4 to receive a fix. For older versions of Requests, use of the .netrc file can be disabled with `trust_env=False` on one's Requests Session.

Mkdocs-material 9.5.5 includes a change in its dependency on Pillow. Previously set to approximately version 9.4, it has now been updated to version 10.22. This change was made in response to the security vulnerability identified as CVE-2023-504477.
https://github.com/squidfunk/mkdocs-material/commit/fe11bc0cabd692d37bc4cc4e8034dbe6783ef36b

MKDocs Material addresses an RXSS vulnerability found in deep links within search results.

Mkdocs-material 9.1.13 includes a fix for a Race Condition Vulnerability. Social plugin triggers the race condition vulnerability when downloading fonts.
https://github.com/squidfunk/mkdocs-material/issues/5515
https://github.com/squidfunk/mkdocs-material/issues/5521

Affected versions of the package djangorestframework are vulnerable to Cross-site Scripting (XSS) via the break_long_headers template filter due to improper input sanitization before splitting and joining with <br> tags.

Tqdm version 4.66.3 addresses CVE-2024-34062, a vulnerability where optional non-boolean CLI arguments like `--delim`, `--buf-size`, and `--manpath` were passed through Python's `eval`, allowing for arbitrary code execution. This security risk, only locally exploitable, has been mitigated in this release. Users are advised to upgrade to version 4.66.3 immediately as there are no workarounds for this issue.

Mkdocs 1.3.0 fixes an XSS vulnerability which was present when using the search function in built-in themes.
https://github.com/mkdocs/mkdocs/commit/5cf196361bb0f8364f667ed98888ffa064982efa

An issue was discovered in Django 4.2 before 4.2.21, 5.1 before 5.1.9, and 5.2 before 5.2.1. The django.utils.html.strip_tags() function is vulnerable to a potential denial-of-service (slow performance) when processing inputs containing large sequences of incomplete HTML tags. The template filter striptags is also vulnerable, because it is built on top of strip_tags().

A potential denial-of-service vulnerability has been identified in Django's urlize() and urlizetrunc() functions in django.utils.html. This vulnerability can be triggered by inputting huge strings containing a specific sequence of characters.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to inefficient string concatenation when processing duplicate HTTP headers in ASGI mode. The ASGIRequest class combines repeated headers using repeated string concatenation, resulting in super-linear (quadratic) time complexity when processing requests with many duplicate headers.

Affected versions of Django are vulnerable to a potential denial-of-service in django.utils.text.wrap(). The django.utils.text.wrap() and wordwrap template filter were subject to a potential denial-of-service attack when used with very long strings.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of control characters in column aliases within FilteredRelation. The FilteredRelation class fails to properly sanitize column aliases containing control characters when used with QuerySet methods annotate(), aggregate(), extra(), values(), values_list(), and alias() via dictionary expansion (**kwargs).

Affected versions of the Django package are vulnerable to SQL Injection due to improper sanitization of band index parameters in PostGIS raster lookups. The raster lookup functionality in Django's GIS module fails to properly validate or escape untrusted data used as a band index when performing spatial queries against PostGIS databases.

Affected versions of the Django package are vulnerable to Denial of Service (DoS) due to quadratic time complexity during HTML parsing in text truncation methods. The django.utils.text.Truncator.chars() and Truncator.words() methods (with html=True), as well as the truncatechars_html and truncatewords_html template filters, exhibit quadratic time complexity when processing inputs containing a large number of unmatched HTML end tags.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled resource consumption during URL parsing on Windows. The URLField.to_python() method invokes urllib.parse.urlsplit(), which performs NFKC normalisation on Windows that is disproportionately slow for certain Unicode characters. A remote attacker can submit large URL inputs containing these characters to forms backed by URLField, causing excessive CPU consumption and rendering the service unavailable.

Affected versions of the Django package are vulnerable to Denial of Service due to uncontrolled memory consumption in the floatformat template filter. The floatformat filter fails to handle string representations of numbers in scientific notation with large exponents efficiently, causing excessive memory allocation when rendering such inputs. An attacker can exploit this by supplying a template with a floatformat filter applied to a specially crafted scientific notation number, leading to memory exhaustion and service unavailability.

Affected versions of Django are vulnerable to Denial-of-Service via django.utils.text.Truncator. The django.utils.text.Truncator chars() and words() methods (when used with html=True) are subject to a potential DoS (denial of service) attack via certain inputs with very long, potentially malformed HTML text. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which are thus also vulnerable. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.

Affected versions of Django are vulnerable to a potential denial-of-service attack due to improper IPv6 validation. The lack of upper limit enforcement for input strings in clean_ipv6_address, is_valid_ipv6_address, and the django.forms.GenericIPAddressField form field allowed attackers to exploit overly long inputs, causing resource exhaustion. The vulnerability is addressed by defining a max_length of 39 characters for affected form fields. The django.db.models.GenericIPAddressField model field was not impacted. Users should upgrade promptly.

Affected versions of Django are vulnerable to potential regular expression denial-of-service (REDoS). django.utils.text.Truncator.words() method (with html=True) and truncatewords_html template filter were subject to a potential regular expression denial-of-service attack using a suitably crafted string (follow up to CVE-2019-14232 and CVE-2023-43665).

Affected versions of Django are affected by a potential denial-of-service vulnerability in the django.utils.html.urlize() function. The urlize and urlizetrunc template filters were susceptible to a denial-of-service attack via certain inputs containing many brackets. An attacker could exploit this vulnerability to cause significant delays or crashes in the affected application.

Django 4.2.7, 4.1.13 and 3.2.23 include a fix for CVE-2023-46695: Potential denial of service vulnerability in UsernameField on Windows.
https://www.djangoproject.com/weblog/2023/nov/01/security-releases

Affected versions of Django has a potential SQL injection vulnerability in the QuerySet.values() and QuerySet.values_list() methods. When used on models with a JSONField, these methods are susceptible to SQL injection through column aliases if a crafted JSON object key is passed as an argument.

Affected versions of the Django package are vulnerable to Path Traversal due to improper validation of archive member paths during extraction. The django.utils.archive.extract() function—used by the startapp --template and startproject --template commands—checked path prefixes instead of using canonicalised paths, allowing archive entries whose names share a prefix with the destination to resolve outside the intended directory.

Affected versions of the Django package are vulnerable to Information Disclosure (Timing Attack) due to non-constant-time comparison in the mod_wsgi authentication handler. The django.contrib.auth.handlers.modwsgi.check_password() function does not perform user existence checks in constant time, allowing response timing differences to reveal whether usernames exist.

Django fixes a potential denial-of-service vulnerability in XML ``Deserializer``.

Affected versions of the Django package are vulnerable to Denial of Service due to inefficient algorithmic complexity in MultiPartParser when handling multipart upload parts that declare Content-Transfer-Encoding: base64 and include excessive whitespace. The parser normalises and decodes the base64 body of each part without bounding the volume of interstitial whitespace, so processing time grows disproportionately with the amount of attacker-supplied whitespace embedded in the encoded payload, reaching a pathological worst case under crafted input. An authenticated remote attacker able to submit multipart uploads can exploit this by including large amounts of whitespace inside a base64-encoded part to consume excessive CPU during request parsing, degrading availability of the Django application.

A security vulnerability has been discovered in certain versions of Django, affecting the password reset functionality. The PasswordResetForm class in django.contrib.auth.forms inadvertently allowed attackers to enumerate user email addresses by exploiting unhandled exceptions during the email sending process. This could be done by issuing password reset requests and observing the responses. Django has implemented a fix where these exceptions are now caught and logged using the django.contrib.auth logger, preventing potential information leakage through error responses.

Affected versions of the Django package are vulnerable to SQL Injection due to improper handling of column aliases containing periods in QuerySet.order_by() when combined with FilteredRelation. The QuerySet.order_by() method fails to properly sanitize column aliases that contain periods when the same alias is used in FilteredRelation via dictionary expansion. 
https://github.com/django/django/commit/90f5b10784ba5bf369caed87640e2b4394ea3314

Affected versions of the Django package are vulnerable to Missing Authorization due to GenericInlineModelAdmin failing to validate add permissions on inline model instances when processing forged POST data on admin change forms. When the admin changes view handles inline formsets backed by GenericInlineModelAdmin, new inline rows submitted in the POST payload are persisted without verifying that the requesting user holds add permission on the target inline model, so the add-permission check is effectively skipped for generic inline relationships. An authenticated admin user who holds change permission on a parent model but lacks add permission on an associated generic-inline model can exploit this by submitting crafted POST data containing additional inline rows, creating new instances of the inline model and resulting in unauthorised record creation within the Django admin.

Affected versions of Django are vulnerable to potential denial-of-service in intcomma template filter when used with very long strings.

Affected versions of Django are affected by a directory-traversal vulnerability in the Storage.save() method. Derived classes of the django.core.files.storage.Storage base class that overrides the generate_filename() method without replicating the file path validations existing in the parent class could allow for directory traversal via certain inputs when calling save().
