The WP Meta SEO plugin for WordPress is vulnerable to unauthorized execution of tasks due to a missing capability check on the startProcess function in versions up to, and including, 4.5.2. This makes it possible for authenticated attackers with subscriber-level access to perform tasks reserved for administratores such as post modifications. This vulnerability occurred as a result of the plugin relying on nonce checks as a means of access control, and that nonce being accessible to all authenticated users regardless of role.
