Description Florencio Cano 2026-10-21 06:28:08 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 3.1.57 fails to guard git option forwarding in IndexFile.checkout() and TagReference.create(), allowing attackers to pass unsafe options via kwargs. Attackers can use --prefix to overwrite arbitrary files with repository content or -F to read arbitrary files returned in-band.
Comment 1 Ben Beasley 2026-10-21 11:10:29 UTC 
This is fixed in 3.1.57, 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.
