Unauthenticated registration enablement via unchecked notice action
Published May 2, 2024 · Updated Apr 8, 2026
Missing authorization in Themeum Tutor LMS 2.6.2 and earlier allows remote attackers to enable disabled WordPress user registration. The hide_notices function accepts registration-related query parameters and updates the users_can_register option without checking administrative capability. No authentication or user interaction is required, and the resulting configuration change permits new account registration rather than granting an existing account administrative privileges.
