CVE-2026-4365

CRITICAL

9.1

Description

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.
