WordPress Plugin Vulnerabilities

Meta Box < 5.11.2 - Contributor+ Arbitrary File Deletion

Description

The plugin is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'ajax_delete_file' function. 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).

Affects Plugins

Fixed in 5.11.2
