Meta Box <= 5.11.1 - Authenticated (Contributor+) Arbitrary File Deletion

7.2
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVE CVE-2025-14675
CVSS 7.2 (High)
Publicly Published March 6, 2026
Last Updated March 7, 2026
Researcher JongHwan Shin (zzzsleep)

Description

The Meta Box plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'ajax_delete_file' function in all versions up to, and including, 5.11.1. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
