Description Florencio Cano 2026-10-21 06:26:45 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 3.1.54 contains an incomplete denylist in unsafe_git_clone_options that omits --template, allowing attackers to achieve arbitrary command execution during clone operations. Attackers can supply --template pointing to a directory containing malicious post-checkout hooks that execute when git clones the repository.

Comment 1 Ben Beasley 2026-10-21 11:10:17 UTC
This is fixed in 3.1.54, which is already in EPEL9 and EPEL10. EPEL8 is at an old version affected by (at this point) dozens of known security issues, but can’t be straightforwardly updated.
