Upgrade GitPython to version 3.2.1 or higher.
Overview
GitPython is a python library used to interact with Git repositories
Affected versions of this package are vulnerable to Incorrect Behavior Order via submodule checkout destination validation in git/objects/submodule/base.py. Submodule checkout destinations can pass the containment check and be accepted before cloning has altered the filesystem, allowing an attacker to place submodule metadata or working-tree content outside the intended repository boundaries. This includes NTFS/HFS metadata-alias bypasses, invalid Windows path components, NUL bytes in submodule names, and destinations nested inside another submodule's Git directory. An attacker who controls a malicious repository can trigger arbitrary path writes on a victim's filesystem when the victim clones or updates submodules.
