 "title": "LearnPress – WordPress LMS Plugin for Create and Sell Online Courses <= 4.4.13 - Unauthenticated Sensitive Information Exposure via List Courses Block 'parsed_block' Parameter",
 "description": "The LearnPress plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'parsed_block' argument of the list courses block AJAX callback in all versions from 4.2.8.4 up to, and including, 4.4.13. This is due to ListCoursesBlockType::render_courses(), which can be called through the public load_content_via_ajax handler, rendering a block tree supplied by the client with new WP_Block() without checking that it came from the server. This makes it possible for unauthenticated attackers to render arbitrary blocks and display content they should not be able to access, such as the content of lessons and quizzes.",
