Critical

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H

The LearnPress plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the delete question answer() function in all versions up to, and including, 4.3.2.8. The plugin exposes a wp rest nonce in public frontend HTML (lpData) to unauthenticated visitors, and uses that nonce as the only security gate for the lp-load-ajax AJAX dispatcher. The delete question answer action has no capability or ownership check. This makes it possible for unauthenticated attackers to delete any quiz answer option by sending a crafted POST request with a publicly available nonce.
