BFG Tools – Extension Zipper <= 1.0.7 - Authenticated (Administrator+) Path Traversal via 'first_file' Parameter

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVE CVE-2025-13681
CVSS Medium (4.9)
Publicly Published February 13, 2026

Researcher Itthidej Aramsri (Boeing777)
Description

The BFG Tools – Extension Zipper plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.0.7. This is due to insufficient input validation on the user-supplied `first_file` parameter in the `zip()` function. This makes it possible for authenticated attackers, with Administrator-level access and above, to read the contents of arbitrary files and directories outside the intended `/wp-content/plugins/` directory, which can contain sensitive information such as wp-config.php.
