Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

Versions of Pip prior to 19.2 are vulnerable to a directory traversal attack during the installation process from a URL. This vulnerability stems from improperly handling filenames in the Content-Disposition header that include path traversal sequences, potentially allowing unauthorized overwrite of critical files such as /root/.ssh/authorized_keys. The flaw is specifically found in the _download_http_url function within _internal/download.py.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.

Aiohttp 3.8.5 includes a fix for CVE-2023-37276: Sending a crafted HTTP request will cause the server to misinterpret one of the HTTP header values leading to HTTP request smuggling.
https://github.com/aio-libs/aiohttp/commit/9337fb3f2ab2b5f38d7e98a194bde6f7e3d16c40
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-45c4-8wx5-qw6w

Affected versions of aiohttp are vulnerable to HTTP Request Smuggling (CWE-444). This vulnerability allows attackers to inject malicious HTTP messages by including line feeds (LF) in chunk extensions, potentially bypassing security controls and executing unauthorized actions. The attack vector involves sending specially crafted chunked HTTP requests to exploit the improper parsing in the HttpPayloadParser class. To mitigate, upgrade to aiohttp version which validates chunk extensions by rejecting any containing unexpected LFs, thereby preventing request smuggling attacks.

Aiohttp 3.8.0 includes a fix for CVE-2023-47641: Affected versions of aiohttp have a security vulnerability regarding the inconsistent interpretation of the http protocol. HTTP/1.1 is a persistent protocol, if both Content-Length(CL) and Transfer-Encoding(TE) header values are present it can lead to incorrect interpretation of two entities that parse the HTTP and we can poison other sockets with this incorrect interpretation. A possible Proof-of-Concept (POC) would be a configuration with a reverse proxy(frontend) that accepts both CL and TE headers and aiohttp as backend. As aiohttp parses anything with chunked, we can pass a chunked123 as TE, the frontend entity will ignore this header and will parse Content-Length. The impact of this vulnerability is that it is possible to bypass any proxy rule, poisoning sockets to other users like passing Authentication Headers, also if it is present an Open Redirect an attacker could combine it to redirect random users to another website and log the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-xx9p-xxvh-7g8j

The vulnerability lies in the improper configuration of static resource resolution when aiohttp is used as a web server. It occurs when the follow_symlinks option is enabled without proper validation, leading to directory traversal vulnerabilities. Unauthorized access to arbitrary files on the system could potentially occur. The affected versions are >1.0.5, and the issue was patched in version 3.9.2. As a workaround, it is advised to disable the follow_symlinks option outside of a restricted local development environment, especially in a server accepting requests from remote users. Using a reverse proxy server to handle static resources is also recommended.
https://github.com/aio-libs/aiohttp/commit/1c335944d6a8b1298baf179b7c0b3069f10c514b

Aiohttp 3.9.0 includes a fix for CVE-2023-49081: Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-q3qx-c6g2-7pw2

Affected versions of aiohttp are vulnerable to an Improper Validation vulnerability. It is possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling).

Affected versions of aiohttp are vulnerable to Middleware Cache Pollution. This vulnerability allows attackers to potentially interfere with middleware handling by exploiting cached middleware associated with system routes. The impact includes possible bypassing of security middleware or unintended access to internal routes. The attack vector involves crafting requests that target system routes, causing the middleware cache to store and reuse inappropriate middleware configurations. The vulnerable methods are _build_middlewares and the middleware caching mechanism in web_app.py. To mitigate, upgrade to aiohttp version, which prevents system routes from polluting the middleware cache by excluding SystemRoute instances from caching.

Affected versions of aiohttp are vulnerable to Directory Traversal (CWE-22). This allows attackers to access sensitive files outside the intended directory by exploiting symbolic links with compressed file extensions. The vulnerability exists in the FileResponse class, where stat() is used instead of lstat(), causing the server to follow symlinks when checking for compressed file variants. To mitigate, update aiohttp to include the fix or modify the code to use lstat() and ensure only regular files are served.

Aiohttp 3.8.0 adds validation of HTTP header keys and values to prevent header injection.
https://github.com/aio-libs/aiohttp/issues/4818

Aiohttp 3.7.4 includes a fix for CVE-2021-21330: In aiohttp before version 3.7.4 there is an open redirect vulnerability. A maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website. It is caused by a bug in the 'aiohttp.web_middlewares.normalize_path_middleware' middleware. A workaround can be to avoid using 'aiohttp.web_middlewares.normalize_path_middleware' in your applications.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-v6wp-4m6f-gcjg

Aiohttp 3.8.6 includes a fix for CVE-2023-47627: The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel).
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg

Affected versions of `aiohttp` are vulnerable to an infinite loop condition. This occurs when an attacker sends a specially crafted POST (multipart/form-data) request. Upon processing, the `aiohttp` server enters an infinite loop, preventing it from processing further requests. This results in a denial-of-service (DoS) attack, allowing an attacker to stop the application from serving requests after a single request. Users are advised to upgrade to version 3.9.4 or manually apply a patch to their systems as per the linked GHSA instructions.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. See CVE-2024-27306.

The aiohttp versions minor than 3.9. has a vulnerability that affects the Python HTTP parser used in the aiohttp library. It allows for minor differences in allowable character sets, which could lead to robust frame boundary matching of proxies to protect against the injection of additional requests. The vulnerability also allows 
 exceptions during validation that aren't handled consistently with other malformed inputs.

Aiohttp 3.8.6 updates vendored copy of  'llhttp' to v9.1.3 to include a security fix.

The impact of this vulnerability is that it is possible to bypass any proxy rule, poisoning sockets to other users like passing Authentication Headers, also if it is present an Open Redirect an attacker could combine it to redirect random users to another website and log the request.

The vulnerability lies in the improper configuration of static resource resolution when aiohttp is used as a web server. It occurs when the follow_symlinks option is enabled without proper validation, leading to directory traversal vulnerabilities. Unauthorized access to arbitrary files on the system could potentially occur. The affected versions are >1.0.5, and the issue was patched in version 3.9.2. As a workaround, it is advised to disable the follow_symlinks option outside of a restricted local development environment, especially in a server accepting requests from remote users. Using a reverse proxy server to handle static resources is also recommended.

Aiohttp 3.9.0 includes a fix for CVE-2023-49081: Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-q3qx-c6g2-7pw2

Affected versions of aiohttp are vulnerable to an Improper Validation vulnerability. It is possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling).

Affected versions of aiohttp are vulnerable to Middleware Cache Pollution. This vulnerability allows attackers to potentially interfere with middleware handling by exploiting cached middleware associated with system routes. The impact includes possible bypassing of security middleware or unintended access to internal routes. The attack vector involves crafting requests that target system routes, causing the middleware cache to store and reuse inappropriate middleware configurations. The vulnerable methods are _build_middlewares and the middleware caching mechanism in web_app.py. To mitigate, upgrade to aiohttp version, which prevents system routes from polluting the middleware cache by excluding SystemRoute instances from caching.

Affected versions of aiohttp are vulnerable to Directory Traversal (CWE-22). This allows attackers to access sensitive files outside the intended directory by exploiting symbolic links with compressed file extensions. The vulnerability exists in the FileResponse class, where stat() is used instead of lstat(), causing the server to follow symlinks when checking for compressed file variants. To mitigate, update aiohttp to include the fix or modify the code to use lstat() and ensure only regular files are served.

Aiohttp 3.8.0 adds validation of HTTP header keys and values to prevent header injection.

Aiohttp 3.7.4 includes a fix for CVE-2021-21330: In aiohttp before version 3.7.4 there is an open redirect vulnerability. A maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website. It is caused by a bug in the 'aiohttp.web_middlewares.normalize_path_middleware' middleware. A workaround can be to avoid using 'aiohttp.web_middlewares.normalize_path_middleware' in your applications.

Aiohttp 3.8.6 includes a fix for CVE-2023-47627: The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel).
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg

Affected versions of `aiohttp` are vulnerable to an infinite loop condition. This occurs when an attacker sends a specially crafted POST (multipart/form-data) request. Upon processing, the `aiohttp` server enters an infinite loop, preventing it from processing further requests. This results in a denial-of-service (DoS) attack, allowing an attacker to stop the application from serving requests after a single request. Users are advised to upgrade to version 3.9.4 or manually apply a patch to their systems as per the linked GHSA instructions.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. See CVE-2024-27306.

The aiohttp versions minor than 3.9. has a vulnerability that affects the Python HTTP parser used in the aiohttp library. It allows for minor differences in allowable character sets, which could lead to robust frame boundary matching of proxies to protect against the injection of additional requests. The vulnerability also allows 
 exceptions during validation that aren't handled consistently with other malformed inputs.

Aiohttp 3.8.6 updates vendored copy of  'llhttp' to v9.1.3 to include a security fix.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

Versions of Pip prior to 19.2 are vulnerable to a directory traversal attack during the installation process from a URL. This vulnerability stems from improperly handling filenames in the Content-Disposition header that include path traversal sequences, potentially allowing unauthorized overwrite of critical files such as /root/.ssh/authorized_keys. The flaw is specifically found in the _download_http_url function within _internal/download.py.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.

As aiohttp parses anything with chunked, we can pass a chunked123 as TE, the frontend entity will ignore this header and will parse Content-Length. The impact of this vulnerability is that it is possible to bypass any proxy rule, poisoning sockets to other users like passing Authentication Headers, also if it is present an Open Redirect an attacker could combine it to redirect random users to another website and log the request.

The vulnerability lies in the improper configuration of static resource resolution when aiohttp is used as a web server. It occurs when the follow_symlinks option is enabled without proper validation, leading to directory traversal vulnerabilities. Unauthorized access to arbitrary files on the system could potentially occur. The affected versions are >1.0.5, and the issue was patched in version 3.9.2. As a workaround, it is advised to disable the follow_symlinks option outside of a restricted local development environment, especially in a server accepting requests from remote users. Using a reverse proxy server to handle static resources is also recommended.

Aiohttp 3.9.0 includes a fix for CVE-2023-49081: Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-q3qx-c6g2-7pw2

Affected versions of aiohttp are vulnerable to an Improper Validation vulnerability. It is possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling).

Affected versions of aiohttp are vulnerable to Middleware Cache Pollution. This vulnerability allows attackers to potentially interfere with middleware handling by exploiting cached middleware associated with system routes. The impact includes possible bypassing of security middleware or unintended access to internal routes. The attack vector involves crafting requests that target system routes, causing the middleware cache to store and reuse inappropriate middleware configurations. The vulnerable methods are _build_middlewares and the middleware caching mechanism in web_app.py. To mitigate, upgrade to aiohttp version, which prevents system routes from polluting the middleware cache by excluding SystemRoute instances from caching.

Affected versions of aiohttp are vulnerable to Directory Traversal (CWE-22). This allows attackers to access sensitive files outside the intended directory by exploiting symbolic links with compressed file extensions. The vulnerability exists in the FileResponse class, where stat() is used instead of lstat(), causing the server to follow symlinks when checking for compressed file variants. To mitigate, update aiohttp to include the fix or modify the code to use lstat() and ensure only regular files are served.

Aiohttp 3.8.0 adds validation of HTTP header keys and values to prevent header injection.

Aiohttp 3.7.4 includes a fix for CVE-2021-21330: In aiohttp before version 3.7.4 there is an open redirect vulnerability. A maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website. It is caused by a bug in the 'aiohttp.web_middlewares.normalize_path_middleware' middleware. A workaround can be to avoid using 'aiohttp.web_middlewares.normalize_path_middleware' in your applications.

Aiohttp 3.8.6 includes a fix for CVE-2023-47627: The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel).
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg

Affected versions of `aiohttp` are vulnerable to an infinite loop condition. This occurs when an attacker sends a specially crafted POST (multipart/form-data) request. Upon processing, the `aiohttp` server enters an infinite loop, preventing it from processing further requests. This results in a denial-of-service (DoS) attack, allowing an attacker to stop the application from serving requests after a single request. Users are advised to upgrade to version 3.9.4 or manually apply a patch to their systems as per the linked GHSA instructions.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. See CVE-2024-27306.

The aiohttp versions minor than 3.9. has a vulnerability that affects the Python HTTP parser used in the aiohttp library. It allows for minor differences in allowable character sets, which could lead to robust frame boundary matching of proxies to protect against the injection of additional requests. The vulnerability also allows 
 exceptions during validation that aren't handled consistently with other malformed inputs.

Aiohttp 3.8.6 updates vendored copy of  'llhttp' to v9.1.3 to include a security fix.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

Versions of Pip prior to 19.2 are vulnerable to a directory traversal attack during the installation process from a URL. This vulnerability stems from improperly handling filenames in the Content-Disposition header that include path traversal sequences, potentially allowing unauthorized overwrite of critical files such as /root/.ssh/authorized_keys. The flaw is specifically found in the _download_http_url function within _internal/download.py.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.

Affected versions of aiohttp are vulnerable to HTTP Request Smuggling (CWE-444). This vulnerability allows attackers to inject malicious HTTP messages by including line feeds (LF) in chunk extensions, potentially bypassing security controls and executing unauthorized actions.

Aiohttp 3.8.0 includes a fix for CVE-2023-47641: Affected versions of aiohttp have a security vulnerability regarding the inconsistent interpretation of the http protocol. HTTP/1.1 is a persistent protocol, if both Content-Length(CL) and Transfer-Encoding(TE) header values are present it can lead to incorrect interpretation of two entities that parse the HTTP and we can poison other sockets with this incorrect interpretation. A possible Proof-of-Concept (POC) would be a configuration with a reverse proxy(frontend) that accepts both CL and TE headers and aiohttp as backend. As aiohttp parses anything with chunked, we can pass a chunked123 as TE, the frontend entity will ignore this header and will parse Content-Length. The impact of this vulnerability is that it is possible to bypass any proxy rule, poisoning sockets to other users like passing Authentication Headers, also if it is present an Open Redirect an attacker could combine it to redirect random users to another website and log the request.

The vulnerability lies in the improper configuration of static resource resolution when aiohttp is used as a web server. It occurs when the follow_symlinks option is enabled without proper validation, leading to directory traversal vulnerabilities. Unauthorized access to arbitrary files on the system could potentially occur. The affected versions are >1.0.5, and the issue was patched in version 3.9.2. As a workaround, it is advised to disable the follow_symlinks option outside of a restricted local development environment, especially in a server accepting requests from remote users. Using a reverse proxy server to handle static resources is also recommended.

Aiohttp 3.9.0 includes a fix for CVE-2023-49081: Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-q3qx-c6g2-7pw2

Affected versions of aiohttp are vulnerable to an Improper Validation vulnerability. It is possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling).

Affected versions of aiohttp are vulnerable to Middleware Cache Pollution. This vulnerability allows attackers to potentially interfere with middleware handling by exploiting cached middleware associated with system routes. The impact includes possible bypassing of security middleware or unintended access to internal routes. The attack vector involves crafting requests that target system routes, causing the middleware cache to store and reuse inappropriate middleware configurations. The vulnerable methods are _build_middlewares and the middleware caching mechanism in web_app.py. To mitigate, upgrade to aiohttp version, which prevents system routes from polluting the middleware cache by excluding SystemRoute instances from caching.

Affected versions of aiohttp are vulnerable to Directory Traversal (CWE-22). This allows attackers to access sensitive files outside the intended directory by exploiting symbolic links with compressed file extensions. The vulnerability exists in the FileResponse class, where stat() is used instead of lstat(), causing the server to follow symlinks when checking for compressed file variants. To mitigate, update aiohttp to include the fix or modify the code to use lstat() and ensure only regular files are served.

Aiohttp 3.8.0 adds validation of HTTP header keys and values to prevent header injection.

Aiohttp 3.7.4 includes a fix for CVE-2021-21330: In aiohttp before version 3.7.4 there is an open redirect vulnerability. A maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website. It is caused by a bug in the 'aiohttp.web_middlewares.normalize_path_middleware' middleware. A workaround can be to avoid using 'aiohttp.web_middlewares.normalize_path_middleware' in your applications.

Aiohttp 3.8.6 includes a fix for CVE-2023-47627: The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel).
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg

Affected versions of `aiohttp` are vulnerable to an infinite loop condition. This occurs when an attacker sends a specially crafted POST (multipart/form-data) request. Upon processing, the `aiohttp` server enters an infinite loop, preventing it from processing further requests. This results in a denial-of-service (DoS) attack, allowing an attacker to stop the application from serving requests after a single request. Users are advised to upgrade to version 3.9.4 or manually apply a patch to their systems as per the linked GHSA instructions.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. See CVE-2024-27306.

The aiohttp versions minor than 3.9. has a vulnerability that affects the Python HTTP parser used in the aiohttp library. It allows for minor differences in allowable character sets, which could lead to robust frame boundary matching of proxies to protect against the injection of additional requests. The vulnerability also allows 
 exceptions during validation that aren't handled consistently with other malformed inputs.

Aiohttp 3.8.6 updates vendored copy of  'llhttp' to v9.1.3 to include a security fix.

Affected versions of Pip are vulnerable to Command Injection. When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

Versions of Pip prior to 19.2 are vulnerable to a directory traversal attack during the installation process from a URL. This vulnerability stems from improperly handling filenames in the Content-Disposition header that include path traversal sequences, potentially allowing unauthorized overwrite of critical files such as /root/.ssh/authorized_keys. The flaw is specifically found in the _download_http_url function within _internal/download.py.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.

Aiohttp 3.8.5 includes a fix for CVE-2023-37276: Sending a crafted HTTP request will cause the server to misinterpret one of the HTTP header values leading to HTTP request smuggling.

A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository. The highest threat from this vulnerability is to data integrity.

An issue was discovered in Pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). A warning was added about this behavior in version 21.1.
NOTE: it has been reported that this is intended functionality and the user is responsible for using --extra-index-url securely.

Pip 21.1 updates its dependency 'urllib3' to v1.26.4 due to security issues.

Versions of Pip prior to 19.2 are vulnerable to a directory traversal attack during the installation process from a URL. This vulnerability stems from improperly handling filenames in the Content-Disposition header that include path traversal sequences, potentially allowing unauthorized overwrite of critical files such as /root/.ssh/authorized_keys. The flaw is specifically found in the _download_http_url function within _internal/download.py.

Pip solves a security vulnerability that previously allowed maliciously crafted wheel files to execute unauthorized code during installation.

Bandit 1.7.7 identifies the str.replace method as a potential risk for SQL injection because it can be misused in constructing SQL queries, potentially enabling the execution of arbitrary SQL code.

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.

Aiohttp 3.8.5 includes a fix for CVE-2023-37276: Sending a crafted HTTP request will cause the server to misinterpret one of the HTTP header values leading to HTTP request smuggling.
https://github.com/aio-libs/aiohttp/commit/9337fb3f2ab2b5f38d7e98a194bde6f7e3d16c40
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-45c4-8wx5-qw6w

Affected versions of aiohttp are vulnerable to HTTP Request Smuggling (CWE-444). This vulnerability allows attackers to inject malicious HTTP messages by including line feeds (LF) in chunk extensions, potentially bypassing security controls and executing unauthorized actions. The attack vector involves sending specially crafted chunked HTTP requests to exploit the improper parsing in the HttpPayloadParser class. To mitigate, upgrade to aiohttp version which validates chunk extensions by rejecting any containing unexpected LFs, thereby preventing request smuggling attacks.

Aiohttp 3.8.0 includes a fix for CVE-2023-47641: Affected versions of aiohttp have a security vulnerability regarding the inconsistent interpretation of the http protocol. HTTP/1.1 is a persistent protocol, if both Content-Length(CL) and Transfer-Encoding(TE) header values are present it can lead to incorrect interpretation of two entities that parse the HTTP and we can poison other sockets with this incorrect interpretation. A possible Proof-of-Concept (POC) would be a configuration with a reverse proxy(frontend) that accepts both CL and TE headers and aiohttp as backend. As aiohttp parses anything with chunked, we can pass a chunked123 as TE, the frontend entity will ignore this header and will parse Content-Length. The impact of this vulnerability is that it is possible to bypass any proxy rule, poisoning sockets to other users like passing Authentication Headers, also if it is present an Open Redirect an attacker could combine it to redirect random users to another website and log the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-xx9p-xxvh-7g8j

The vulnerability lies in the improper configuration of static resource resolution when aiohttp is used as a web server. It occurs when the follow_symlinks option is enabled without proper validation, leading to directory traversal vulnerabilities. Unauthorized access to arbitrary files on the system could potentially occur. The affected versions are >1.0.5, and the issue was patched in version 3.9.2. As a workaround, it is advised to disable the follow_symlinks option outside of a restricted local development environment, especially in a server accepting requests from remote users. Using a reverse proxy server to handle static resources is also recommended.

Aiohttp 3.9.0 includes a fix for CVE-2023-49081: Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request.
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-q3qx-c6g2-7pw2

Affected versions of aiohttp are vulnerable to an Improper Validation vulnerability. It is possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling).

Affected versions of aiohttp are vulnerable to Middleware Cache Pollution. This vulnerability allows attackers to potentially interfere with middleware handling by exploiting cached middleware associated with system routes. The impact includes possible bypassing of security middleware or unintended access to internal routes. The attack vector involves crafting requests that target system routes, causing the middleware cache to store and reuse inappropriate middleware configurations. The vulnerable methods are _build_middlewares and the middleware caching mechanism in web_app.py. To mitigate, upgrade to aiohttp version, which prevents system routes from polluting the middleware cache by excluding SystemRoute instances from caching.

Affected versions of aiohttp are vulnerable to Directory Traversal (CWE-22). This allows attackers to access sensitive files outside the intended directory by exploiting symbolic links with compressed file extensions. The vulnerability exists in the FileResponse class, where stat() is used instead of lstat(), causing the server to follow symlinks when checking for compressed file variants. To mitigate, update aiohttp to include the fix or modify the code to use lstat() and ensure only regular files are served.

Aiohttp 3.8.0 adds validation of HTTP header keys and values to prevent header injection.

Aiohttp 3.7.4 includes a fix for CVE-2021-21330: In aiohttp before version 3.7.4 there is an open redirect vulnerability. A maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website. It is caused by a bug in the 'aiohttp.web_middlewares.normalize_path_middleware' middleware. A workaround can be to avoid using 'aiohttp.web_middlewares.normalize_path_middleware' in your applications.

Aiohttp 3.8.6 includes a fix for CVE-2023-47627: The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel).
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg

Affected versions of `aiohttp` are vulnerable to an infinite loop condition. This occurs when an attacker sends a specially crafted POST (multipart/form-data) request. Upon processing, the `aiohttp` server enters an infinite loop, preventing it from processing further requests. This results in a denial-of-service (DoS) attack, allowing an attacker to stop the application from serving requests after a single request. Users are advised to upgrade to version 3.9.4 or manually apply a patch to their systems as per the linked GHSA instructions.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. See CVE-2024-27306.

The aiohttp versions minor than 3.9. has a vulnerability that affects the Python HTTP parser used in the aiohttp library. It allows for minor differences in allowable character sets, which could lead to robust frame boundary matching of proxies to protect against the injection of additional requests. The vulnerability also allows 
 exceptions during validation that aren't handled consistently with other malformed inputs.

Aiohttp 3.8.6 updates vendored copy of  'llhttp' to v9.1.3 to include a security fix.
