CVE-2026-4365 Details
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.
A vulnerability exists in the LearnPress WordPress plugin, in all versions through 4.3.2.8, allowing unauthorized deletion of quiz answers. This issue arises from a lack of capability checks in the 'delete_question_answer()' function. The plugin exposes a 'wp_rest' nonce in public frontend HTML, which is used as the sole security measure for the 'lp-load-ajax' AJAX dispatcher. Without any capability or ownership checks, unauthenticated attackers can delete quiz answer options by sending a POST request with the publicly available nonce.
Users are advised to update the LearnPress WordPress plugin to version 4.3.3 or a newer patched version.
