CVE-2026-110859 is fixed in python-git on 1 platform, first by DEBIAN-CVE-2026-110859, released October 25, 2026. It is not reported as exploited. Patch Radar priority: Routine.
GitPython before 3.2.0 contains an argument injection vulnerability in Head.checkout() that allows remote attackers to read arbitrary files by supplying a branch name parsed as a git option. Attackers can host a repository whose default branch is named --pathspec-from-file=<path>, causing cloning applications that check out the active branch to leak file contents through GitCommandError messages.
