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 checkanswer. 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.
