Patool before 4.0.5 contains a path traversal vulnerability in the safe extract() function in patoolib/programs/py tarfile.py when running on Python before 3.12, where the is within directory() helper uses os.path.commonprefix() for character-level string comparison instead of path-level comparison, allowing a crafted archive member path to bypass the containment check. Attackers can supply a malicious archive with specially crafted member paths to write arbitrary files.
