NVD Description

Note: Versions mentioned in the description apply only to the upstream renovate package and not the renovate package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

node-tar is a full-featured Tar for Node.js. Prior to version 7.5.11, tar (npm) can be tricked into creating a symlink that points outside the extraction directory by using a drive-relative symlink target such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This vulnerability is fixed in 7.5.11.
