Last modified

CVE-2026-24842 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. node-tar,a Tar for Node.js, contains a vulnerability in versions prior to 7.5.7 where the security check for hardlink entries uses different path resolution semantics than the actual hardlink creation logic. This mismatch allows an attacker to craft a malicious TAR archive that bypasses path traversal protections and creates hardlinks to arbitrary files outside the extraction directory. EPSS estimates a 0.54% chance of exploitation in the next 30 days.
