Description Thomas Eagle 2026-08-14 19:53:10 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 is a python library used to interact with Git repositories. Prior to version 3.1.49, GitConfigParser.set_value() passes values to Python's configparser without validating for newlines. GitPython's own _write() converts embedded newlines into indented continuation lines (e.g. \n becomes \n\t), but Git still accepts an indented [core] stanza as a section header — so the injected core.hooksPath becomes effective configuration. Any Git operation that invokes hooks (commit, merge, checkout) will then execute scripts from the attacker-controlled path. This issue has been patched in version 3.1.49.
Comment 1 Ben Beasley 2026-08-16 13:11:44 UTC 
This is fixed in 3.1.49, 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.
