Impact
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.
