Attackers can exploit the publicly accessible load_content_via_ajax REST route, which only requires a public wp_rest nonce, to add or remove courses from any user's wishlist and determine whether a given course is wishlisted by iterating user_id and course_id values.","summary":"The LearnPress Course Wishlist add-on trusts a user_id parameter instead of the logged-in session, so remote attackers can add or remove courses from any user's wishlist.
