node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This issue has been patched in version 7.5.10.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1483 advisory.

    node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an     attacker-controlled archive can create a hardlink inside the extraction directory that points to a file     outside the extraction root, enabling arbitrary file read and write as the extracting user. Severity is     high because the primitive bypasses path protections and turns archive extraction into a direct filesystem     access primitive. This issue has been fixed in version 7.5.8. (CVE-2026-26960)

    A vulnerability was found in juliangruber brace-expansion up to 1.1.11/2.0.1/3.0.0/4.0.0. It has been     rated as problematic. Affected by this issue is the function expand of the file index.js. The manipulation     leads to inefficient regular expression complexity. The attack may be launched remotely. The complexity of     an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the     public and may be used. Upgrading to version 1.1.12, 2.0.2, 3.0.1 and 4.0.1 is able to address this issue.
    The name of the patch is a5b98a4f30d7813266b221435e1eaaf25a1b0ac5. It is recommended to upgrade the     affected component. (CVE-2025-5889)
