CVE-2026-76220
8.7
CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
GitPython before 3.1.58 contains a command execution vulnerability in the check_unsafe_options guard that can be bypassed by combining a single-character kwarg with split_single_char_options=False. Attackers can supply a crafted kwargs dictionary to guarded methods like clone_from to emit a joined token parsed as –upload-pack, enabling arbitrary OS command execution at default allow_unsafe_options=False.
