    CVE-2026-29509 (GCVE-0-2026-29509)

    Vulnerability from nvd – Published: 2026-06-26 19:31 – Updated: 2026-06-27 03:03 X_Open Source
    VLAI
    Title
    Patool < 4.0.5 Path Traversal via safe_extract() Function
    Summary
    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.
