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).

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.

Pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example ‘setup_requires’ and ‘tests_require’ bypass pip --require-hashes. See also pypa/setuptools#1684.
It is recommended that you:
- Remove 'pytest-runner' from your setup_requires, preferably removing the setup_requires option.
- Remove 'pytest' and any other testing requirements from tests_require, preferably removing the tests_requires option.
- Select a tool to bootstrap and then run tests such as tox.

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.

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.

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

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.

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.

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.

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.

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).

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 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 3.8.5 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.

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.

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.

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).

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

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.

Pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example ‘setup_requires’ and ‘tests_require’ bypass pip --require-hashes. See also pypa/setuptools#1684.
It is recommended that you:
- Remove 'pytest-runner' from your setup_requires, preferably removing the setup_requires option.
- Remove 'pytest' and any other testing requirements from tests_require, preferably removing the tests_requires option.
- Select a tool to bootstrap and then run tests such as tox.

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.

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.

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

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.

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 3.9.0 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.

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 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 3.8.5 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/security/advisories/GHSA-pjjw-qhg8-p2p9

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.

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.

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).

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

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.

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.

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.

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

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.
