TIMELINE Mar 4 Reserved by GitHub_M Mar 7 Published (CNA: GitHub_M) Sep 1 EXPLOIT PUBLISHED — CVE-2026-29786 (isaacs node-tar). Public exploit reference added.
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.
