Technical details
The PUT and DELETE /:lessonId routes lack proper role-based access control and only verify course membership without checking if the user has instructor or administrator privileges. An authenticated user can supply arbitrary lesson IDs to modify titles, stored HTML content, or delete lessons regardless of their role (student vs. instructor). This is an authorization bypass affecting any authenticated course member.
