Upgrade GitPython to version 3.2.0 or higher.
Overview
GitPython is a python library used to interact with Git repositories
Affected versions of this package are vulnerable to Symlink Attack via Submodule.move() in git/objects/submodule/base.py, which validates the destination path only lexically using abspath(), commonpath(), and relpath(), without resolving or rejecting symbolic links in intermediate path components. An untrusted repository can commit a mode-120000 symlink (e.g., vendor -> ../outside) so that when an application calls submodule.move("vendor/module") with a fixed destination, the operating system resolves vendor through the attacker-committed symlink, relocating the submodule checkout to an external directory, rewriting .gitmodules and the index to the symlinked path, and leaving the index unable to produce a tree.
Note: This is only exploitable on systems where Git materializes tracked symlinks as real filesystem symlinks; on Windows this generally requires core.symlinks=true with Developer Mode or sufficient privilege, and the application must explicitly call Submodule.move() with a path beneath the attacker-committed symlink.
