patool before 4.0.6 OS Command Injection on Windows via shell_quote_nt
patool before 4.0.6 contains an OS command injection vulnerability on Windows because shell_quote_nt fails to escape cmd.exe metacharacters or embedded double quotes in archive filenames.

CWE-22 Jun 26, 2026
Patool < 4.0.5 Path Traversal via safe_extract() Function
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.
