Creator LMS – WordPress LMS Plugin for Coaches, Cohorts & Course Creators <= 1.2.19 - Authenticated (Subscriber+) Free Paid Course Enrollment
The Creator LMS – WordPress LMS Plugin for Coaches, Cohorts & Course Creators plugin for WordPress is vulnerable to Payment Bypass in all versions up to, and including, 1.2.19. This is due to missing server-side validation of the attacker-supplied `purchase_by` parameter in the cart and checkout flow, allowing the point-purchase flag to be stored in the session and honoured at checkout regardless of whether the course supports point purchasing or the user holds enough points. This makes it possible for authenticated attackers, with subscriber-level access and above, to enroll in paid courses for free by supplying a forged `purchase_by=point` value that causes the checkout to skip payment entirely, even when point purchasing is not configured or the user has an insufficient balance.
