CVE-2026-24842: node-tar Vulnerable to Arbitrary File Creation/Overwrite via Hardlink Path Traversal
node-tar contains a vulnerability 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.
