Pypa Security Vulnerabilities

CVE-2013-1629

pip before 1.3 uses HTTP to retrieve packages from the PyPI repository, and does not perform integrity checks on package contents, which allows man-in-the-middle attackers to execute arbitrary code via a crafted response to a "pip install" operation.

CVE-2013-1888

pip before 1.3 allows local users to overwrite arbitrary files via a symlink attack on a file in the /tmp/pip-build temporary directory.

CVE-2013-5123

The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks.

CVE-2014-8991

pip 1.3 through 1.5.6 allows local users to cause a denial of service (prevention of package installation) by creating a /tmp/pip-build-* file for another user.

CVE-2018-20225

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 a...

CVE-2019-20916

The pip package before 19.2 for Python allows Directory Traversal when a URL is given in an install command, because a Content-Disposition header can have ../ in a filename, as demonstrated by overwriting the /root/.ssh/authorized_keys file. This occurs in _download_http_url in _internal/download.p...

CVE-2021-3572

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. This is fixed in python-pip version 21.1.

CVE-2022-21668

pipenv is a Python development workflow tool. Starting with version 2018.10.9 and prior to version 2022.1.8, a flaw in pipenv's parsing of requirements files allows an attacker to insert a specially crafted string inside a comment anywhere within a requirements.txt file, which will cause victims wh...

CVE-2023-5752

When installing a package from a Mercurial VCS URL (ie "pip installhg+...") with pip prior to v23.3, the specified Mercurial revision couldbe used to inject arbitrary configuration options to the "hg clone"call (ie "--config"). Controlling the Mercurial configuration can modifyhow and which reposit...

CVE-2024-6345

A vulnerability in the package_index module of pypa/setuptools versions up to 69.1.1 allows for remote code execution via its download functions. These functions, which are used to download packages from URLs provided by users or retrieved from package index servers, are susceptible to code injecti...
