AZL-79553 CVE-2026-29786 affecting package tar 1.35-2

node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x extraction. Th...

CVE-2026-26960

A flaw was found in node-tar. An attacker can craft a malicious archive that, when extracted with default options, creates a hardlink outside the intended extraction directory. This vulnerability allows the attacker to perform arbitrary file read and write operations as the user extracting the...

Path Traversal

node-tar is vulnerable to Path Traversal. The vulnerability is due to inconsistent path resolution between hardlink security checks and hardlink creation logic, allowing a malicious TAR archive to bypass extraction directory restrictions and create hardlinks to arbitrary files outside the intende...

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...
