52th percentile - higher than 52% of all known CVEs

Summary

The zip-lib library before version 1.1.0 is vulnerable to Directory Traversal via the caching mechanism for path validation during extraction. An attacker can bypass security checks because the isOutsideTargetFolder function only validates the path when the initial symlink is created.

Risk Assessment

An attacker can overwrite or read files outside the target directory, potentially leading to privilege escalation or data leakage.

Recommendation

Update the zip-lib library to version 1.1.0 or later.

Original NVD description (English source)

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. An attacker can bypass security checks designed to prevent directory traversal. The intended security function, isOutsideTargetFolder, only checks and caches the path status when the initial directory symlink is created during the first extraction.
