The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized deletion of quiz question answers due to a missing capability check in the delete_question_answer() function of the EditQuestionAjax class in all versions up to, and including, 4.3.2.8. The AbstractAjax::catch_lp_ajax() dispatcher verifies a wp_rest nonce but performs no current_user_can() check, and the QuestionAnswerModel::delete() method only validates minimum answer counts without checking user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete answer options from any quiz question on the site.
