Input validation vulnerability in Restrict File Access 1.1.2

A security issue has been found in the Restrict File Access plugin for WordPress. This vulnerability affects all versions up to and including 1.1.2. The problem is that the plugin does not properly check for a security code when accessing the ‘restrict-file-access’ page. As a result, someone without authorization can delete any files on the server, including important ones like wp-config.php. This could potentially allow them to remotely execute code on the site if they can trick the site administrator into clicking on a link.
