DescriptionGitHub Advisory

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 hardlinks and Symlink Poisoning via absolute symlink targets. This vulnerability is fixed in 7.5.3.

AnalysisAI

node-tar versions 7.5.2 and earlier fail to properly sanitize link paths in tar archives when the default secure mode is enabled, allowing attackers to extract files outside the intended directory through malicious hardlinks and symlinks. Public exploit code exists for this vulnerability, which affects Node.js applications and related products including D-Link and Tar utilities. …
