CVE-2026-67325GitPython before 3.1.51 Command Injection via option prefix abbreviation
High 8.8
In plain English
A high-severity OS command injection in GitPython from gitpython-developers. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 2.2% (higher than 83% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
GitPython before 3.1.51 contains an incomplete command injection blocklist that fails to account for git's long-option prefix abbreviation feature. Attackers can bypass the unsafe options guard by using abbreviated option names like upload_p instead of upload_pack, which git resolves to dangerous options and executes arbitrary commands.
