Description Marian Rehak 2026-09-10 11:39:35 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 3.1.60 fails to properly validate the git directory location, allowing attackers to impersonate the git directory using tracked files like gitdir, commondir, and HEAD. Attackers can execute arbitrary code by placing a malicious pre-commit hook in the tracked hooks directory that executes when a victim calls index.commit() on a cloned or opened repository.
Comment 1 Ben Beasley 2026-09-10 18:53:21 UTC 
This is fixed in 3.1.60, 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.
