Duplicate Advisory: GitPython: Command Injection via git long-option prefix abbreviation bypass of CVE-2026-42215 blocklist

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-2f96-g7mh-g2hx. This link is maintained to preserve external references.

Original 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.
