Description

GitPython before 3.1.58 fails to validate submodule names from .gitmodules files, allowing attackers to create Git repositories at arbitrary filesystem paths outside the intended clone directory. Attackers can craft malicious repositories with traversal sequences in submodule names that GitPython processes during submodule initialization, creating attacker-controlled Git repositories at escaped filesystem locations.

• CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
