GitPython versions before 3.1.54 contain a remote code execution vulnerability in the checkunsafeoptions guard that can be bypassed by smuggling git options inside single-character kwarg values. Attackers can supply crafted option dictionaries to clonefrom, fetch, pull, push, lsremote, itercommits, blame, or archive methods to execute arbitrary OS commands via the --upload-pack parameter.
