CVE-2026-110856 is fixed in python-git on 1 platform, first by DEBIAN-CVE-2026-110856, released October 25, 2026. It is not reported as exploited. Patch Radar priority: Routine.
GitPython before 3.2.0 contains a regular expression denial of service vulnerability in the _re_actor_epoch pattern used by parse_actor_and_date on author, committer, and tagger lines. Attackers can serve repositories with commit or tag objects containing long space-filled lines lacking a valid epoch or timezone, causing quadratic backtracking and CPU exhaustion.
