CVE-2026-17524
NVD: Versions of the package zip-lib before 1.1.0 are vulnerable to Directory Traversal via the caching mechanism for path validation during the extraction process. NVD: An attacker can bypass security checks designed to prevent directory traversal. NVD: The intended security function, isOutsideTargetFolder, only checks and caches the path status when the initial directory symlink is created during the first extraction.
