GitPython before 3.1.58 contains a command execution vulnerability in the checkunsafeoptions guard that can be bypassed by combining a single-character kwarg with splitsinglecharoptions=False. Attackers can supply a crafted kwargs dictionary to guarded methods like clonefrom to emit a joined token parsed as --upload-pack, enabling arbitrary OS command execution at default allowunsafeoptions=False.
