How to fix?

Upgrade Minimos:latest py3.13-gitpython to version 3.1.58-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3.13-gitpython package and not the py3.13-gitpython package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
