Description
The Modula Image Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'ajax_unzip_file' function in versions 2.13.1 to 2.13.2. This makes it possible for authenticated attackers, with Author-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).
