Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2025-13681

Medium
4.9/10

Summary

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.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
