stated named in the record

The LearnPress plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the function in all versions up to, and including, 4.3.2.8. The plugin exposes a nonce in public frontend HTML ( ) to unauthenticated visitors, and uses that nonce as the only security gate for the AJAX dispatcher.
