The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.4.1 via the check_answer. This makes it possible for unauthenticated attackers to extract the correct-answer markers, full option lists, explanations, and question content for any quiz question on the site — including questions belonging to paid courses the attacker is not enrolled in.
