Advisory
Source description from Wordfence Intelligence, credited to James Golovich.
The WP Ultimate CSV Importer plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the templates/readfile.php file in versions up to, and including, 3.7. This makes it possible for unauthenticated attackers to read any files on the vulnerable service that PHP has access to.
