CVE-2026-67325

GitPython before 3.1.51 Command Injection via option prefix abbreviation

Published Aug 1, 2026 CVSS 4.0 · 8.7 High EPSS 2.2% KEV · Not listed
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.
