Description Florencio Cano 2026-10-21 06:29:30 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 3.1.55 fails to disable environment variable expansion in Remote.create() and Submodule.add() URL handling, allowing attackers to exfiltrate secrets by supplying URLs containing variable references. Attackers can craft URLs with environment variable tokens that are expanded into .git/config and .gitmodules, then transmitted to attacker-controlled hosts during fetch or pull operations.

Comment 1 Ben Beasley 2026-10-21 11:11:14 UTC

This is fixed in 3.1.55, 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.
