High · CVSS 8.6 (CVSS 3.1)EPSS 0.47%, 40th percentilePublished Updated Assigner: GitHub_M

Description

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.
