Update, patch or deactivate.

No fixed release is identified. Update Tutor LMS – eLearning and online course solution when a release after 3.9.7 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 4.0.5, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized private course enrollment in all versions up to, and including, 3.9.7. This is due to missing post_status validation in the `enroll_now()` and `course_enrollment()` functions. Both enrollment endpoints verify the nonce, user authentication, and whether the course is purchasable, but fail to check if the course has a `private` post_status. This makes it possible for authenticated attackers with Subscriber-level access or above to enroll in private courses by sending a crafted POST request with the target course ID. The enrollment record is created in the database and the private course title and enrollment status are exposed in the subscriber's dashboard, though WordPress core access control prevents the subscriber from viewing the actual course content (returns 404). Enrollment in private courses should be restricted to users with the `read_private_posts` capability.
