CVE-2026-24842

A flaw was found in node-tar, a Node.js module for handling TAR archives. This vulnerability allows a remote attacker to bypass path traversal protections by crafting a malicious TAR archive. The security check for hardlink entries uses different path resolution logic than the actual hardlink creation, enabling the attacker to create hardlinks to arbitrary files outside the intended extraction directory. This could lead to unauthorized information disclosure or further system compromise.
