Description nlevinki 2026-09-27 10:45:29 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
Comment 1 Ben Beasley 2026-09-28 06:56:18 UTC 
This is fixed in 3.1.59, which is already in all Fedora branches, EPEL10, and EPEL9. EPEL8 is at an old version affected by (at this point) dozens of known security issues, but can’t be straightforwardly updated.
