CVE-2026-78677: Gitpython Project Gitpython

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

GitPython before 3.1.59 omits --separate-git-dir from unsafe_git_clone_options, allowing attackers to create arbitrary git directories outside the intended clone destination. Attackers can pass a separate_git_dir parameter to Repo.clone_from() or Repo.clone() to redirect repository metadata to an attacker-controlled filesystem path, enabling arbitrary directory creation and potential hook execution.

Affected products

• Gitpython Project Gitpython: before 3.1.59 (fixed in 3.1.59)
