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.
