CVE-2026-67325: GitPython before 3.1.51 Command Injection via option prefix abbreviation

Published Aug 1, 2026
·
Updated

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 uploadp instead of uploadpack, which git resolves to dangerous options and executes arbitrary commands.

Affected Software

1 affected component
GitPython GitPython<3.1.51

Remediation

Recommended actions to resolve this vulnerability, in priority order.

  1. Upgrade

    Upgrade GitPython to a version that resolves this vulnerability.

    Fixed in 3.1.51
  2. Compensating control

    Use a GitPython version at or after 3.1.51 to prevent command injection via option prefix abbreviation (e.g., abbreviated option names like upload_p resolving to upload_pack).
