Description

 - node-tar is a Tar for Node.js. The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link
 (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows
 malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via
