AI-suggested

A fix is available in node-tar version 7.5.7. Users and vendors should upgrade to this version or later to remediate the vulnerability. Red Hat advisories indicate that no effective mitigation other than upgrading currently meets their criteria for ease of use and applicability. Therefore, upgrading to a fixed version is the recommended remediation.

Description

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. Version 7.5.7 contains a fix for the issue.
