CVE ID : CVE-2026-26960
Published : Feb. 20, 2026, 1:07 a.m. | 1 hour, 15 minutes ago
Description : node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file read and write as the extracting user. Severity is high because the primitive bypasses path protections and turns archive extraction into a direct filesystem access primitive. This issue has been fixed in version 7.5.8.
Severity: 0.0 | NA
