Package        : node-tar
Version        : 6.1.13+~cs7.0.5-1+deb12u1
CVE ID         : CVE-2024-28863 CVE-2026-23745 CVE-2026-26960 CVE-2026-29786

Multiple vulnerabilities have been discovered in node-tar, a Node.js
module to read and write portable tar archives.

CVE-2024-28863

   Generating a large number of sub-folders can consume memory on the
   system and even crash the Node.js client within a few seconds using
   a path with too many sub-folders inside.

CVE-2026-23745

   When preservePaths is false, the linkpath of Link (hardlink) and
   SymbolicLink entries fail to be sanitized, allowing malicious
   archives to bypass the extraction root restriction, leading to
   arbitrary file overwrites via hardlinks and symlink poisoning via
   absolute symlink targets.
   
   The fix for this issue introduces CVE-2026-24842 and CVE-2026-31802.
   Both have been fixed subsequently.


CVE-2026-26960

   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.

CVE-2026-29786

   An attacker-controlled archive can create a hardlink that points
   outside the extraction directory by using a drive-relative link
   target. 

For Debian 12 bookworm, these problems have been fixed in version
6.1.13+~cs7.0.5-1+deb12u1.

We recommend that you upgrade your node-tar packages.
