Ecosystem-wide dependent count for version 7.5.10.

DescriptionGitHub Advisory

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.

AnalysisAI

Path traversal in node-tar versions prior to 7.5.10 allows local attackers to write files outside the intended extraction directory by exploiting drive-relative link targets during archive extraction. An attacker with the ability to create or modify tar archives can overwrite arbitrary files on the system with elevated privileges. …
