About this tag
Discussions on WindowsForum.com about the node tar package focus on two high-severity vulnerabilities: CVE-2026-29786 and CVE-2026-26960. Both involve hardlink escape flaws that allow a maliciously crafted tar archive to write or read files outside the intended extraction directory. CVE-2026-29786 exploits drive-relative hardlink targets like C:../target.txt, while CVE-2026-26960 enables arbitrary file read/write. These issues affect the widely used Node.js tar library (npm package tar) and are fixed in versions 7.5.8 and later. The vulnerabilities are relevant for any system, CI pipeline, container, or application that extracts untrusted tar archives using vulnerable node-tar versions.
