Path traversal in GitPython - CVE-2026-44243

Vulnerability identifier: #VU128348

CSH Severity: Low

CVSS v4: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-44243

CWE-ID: CWE-22

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to write, overwrite, move, or delete files outside the repository's .git directory.

The vulnerability exists due to path traversal in GitPython reference APIs when processing application-controlled reference paths in reference creation, rename, and delete operations. A local user can supply a crafted reference path to write, overwrite, move, or delete files outside the repository's .git directory.

Exploitation requires the ability to influence reference names supplied by the consuming application.
