GHSA-XMJ3-9GF7-H52W setuptools: Windows path escape via namespace_packages.txt during legacy wheel installation Description

Summary On Windows, attacker-controlled content in a wheel's .dist-info/namespacepackages.txt can cause setuptools' legacy wheel installation path to create an init.py outside the requested destinationeggdir. The attacker can influence the destination path, but not the contents of the created fil...

Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value via the seed wheel acquisition logic in src/virtualenv/seed/wheels/acquire.py and pipinvoke.py, where wheels are cached and then passed to pip for installation without verifying their integri...

PYSEC-2026-4305 uv: Path traversal on Windows through wheel extraction

Impact In versions of uv from 0.12.7 to 0.12.18 on Windows, uv could be induced into writing a file outside of the installation prefix during wheel installation. A malicious wheel could use this to place an executable outside of the intended environment, including in a directory already present o...

CVE-2026-47764

Summary of CVE-2026-47764 (pdm) : A path-traversal vulnerability in wheel installation arises from InstallDestination.write_to_fs() in src/pdm/installers/installers.py, where a safe validation helper (_path_with_destdir()) was replaced with a bare os.path.join(), removing path validation. Version...

CVE-2026-47764 pdm: Path traversal in wheel installation via overridden write_to_fs

pdm is a Python package and dependency manager supporting the latest PEP standards. Versions prior to 2.27.0 are vulnerable to path traversal through writetofs. InstallDestination.writetofs in src/pdm/installers/installers.py overrides the base class to add symlink/hardlink support but replaces t...

python-pip: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite

A flaw was found in pip, the package installer for Python. A remote attacker can exploit this vulnerability by tricking a victim into installing a malicious Python wheel. This wheel contains specially crafted entry-point names that use directory traversal or absolute paths. This allows pip to wri...
