Mine CloudVod < 2.6.7 - Unauthenticated Paid Lesson Content Disclosure

The Mine CloudVod WordPress plugin before 2.6.7 does not check whether the requester is enrolled in a course, or authorised at all, before returning the course's full curriculum together with the raw content of every published lesson, allowing unauthenticated visitors to retrieve paid lesson content, such as direct video source URLs, and the passwords of password-protected lessons.
