pip's fallback tar extraction doesn't check symbolic links point to extraction directory

CVE-2025-8869 / GHSA-4xh5-x5gv-qwph

More information

Details

When extracting a tar archive pip may not check symbolic links point into the extraction directory if the tarfile module doesn't implement PEP 706. Note that upgrading pip to a "fixed" version for this vulnerability doesn't fix all known vulnerabilities that are remediated by using a Python version that implements PEP 706. Note that this is a vulnerability in pip's fallback implementation of tar extraction for Python versions that don't implement PEP 706 and therefore are not secure to all vulnerabilities in the Python 'tarfile' module. If you're using a Python version that implements PEP 706 then pip doesn't use the "vulnerable" fallback code. Mitigations include upgrading to a version of pip that includes the fix, upgrading to a Python version that implements PEP 706 (Python >=3.9.17, >=3.10.12, >=3.11.4, or >=3.12), applying the linked patch, or inspecting source distributions (sdists) before installation as is already a best-practice.

pip Path Traversal vulnerability

CVE-2026-1703 / GHSA-6vgw-5pg2-w6jp

More information

Details

When pip is installing and extracting a maliciously crafted wheel archive, files may be extracted outside the installation directory. The path traversal is limited to prefixes of the installation directory, thus isn't able to inject or overwrite executable files in typical situations.

Severity

pip has an interpretation conflict due to handling both concatenated tar and ZIP files as ZIP files

CVE-2026-3219 / GHSA-58qw-9mgm-455v

More information

Details

pip handles concatenated tar and ZIP files as ZIP files regardless of filename or whether a file is both a tar and ZIP file. This behavior could result in confusing installation behavior, such as installing "incorrect" files according to the filename of the archive. New behavior only proceeds with installation if the file identifies uniquely as a ZIP or tar archive, not as both.

pip Vulnerable to Inclusion of Functionality from Untrusted Control Sphere

CVE-2026-6357 / GHSA-jp4c-xjxw-mgf9

More information

Details

pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.

Severity

• CVSS Score: 5.3 / 10 (Medium)
