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."}], "lastModified": "2026-04-22T20:23:16.350", "sourceIdentifier": "security@wordfence.com"}
