LearnPress < 4.4.7 - Unauthenticated Student Enrollment Disclosure via load_content_via_ajax

The LearnPress WordPress plugin before 4.4.7 does not check the user's capabilities in one of its administrative course tools, allowing unauthenticated attackers to list every enrolled student's display name and user identifier against the course they are enrolled on, and to recover their email addresses through the same handler's search filter.
