    CVE-2026-106057 (GCVE-0-2026-106057)

    Vulnerability from nvd – Published: 2026-10-07 11:59 – Updated: 2026-10-07 14:43
    VLAI
    Title
    patool before 4.0.6 OS Command Injection on Windows via shell_quote_nt
    Summary
    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. Attackers can supply crafted filenames like report&calc.gz for single-file formats run with shell=True to execute commands with patool process privileges.

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

    Vulnerability from nvd – Published: 2026-06-26 19:31 – Updated: 2026-07-14 18:39 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.

    Title
    patool before 4.0.6 OS Command Injection on Windows via shell_quote_nt
    Summary
    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. Attackers can supply crafted filenames like report&calc.gz for single-file formats run with shell=True to execute commands with patool process privileges.

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

    Vulnerability from cvelistv5 – Published: 2026-06-26 19:31 – Updated: 2026-07-14 18:39 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.
