Detailsinfo

A vulnerability was found in gitpython-developers GitPython up to 3.1.47. It has been classified as critical. Affected is an unknown code. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on integrity, and availability. CVE summarizes:

GitPython is a python library used to interact with Git repositories. Prior to version 3.1.48, a vulnerability in GitPython allows attackers who can supply a crafted reference path to an application using GitPython to write, overwrite, move, or delete files outside the repository’s .git directory via insufficient validation of reference paths in reference creation, rename, and delete operations. This issue has been patched in version 3.1.48.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-44243 since 05/05/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.
