Description Jon Weiser 2026-08-27 20:39:56 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 3.1.58 contains a command execution vulnerability in the check_unsafe_options guard that can be bypassed by combining a single-character kwarg with split_single_char_options=False. Attackers can supply a crafted kwargs dictionary to guarded methods like clone_from to emit a joined token parsed as --upload-pack, enabling arbitrary OS command execution at default allow_unsafe_options=False.
Comment 1 Ben Beasley 2026-08-27 21:09:31 UTC 
GitPython >=3.1.58 is already in all EPEL branches, except EPEL8 where it cannot be updated.
