CVE-2026-4365

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.
