⚠️ A simple tweak in the user-role value can sneak an attacker right into the Coursemill LMS! Imagine letting in a guest who claims to be the host — that’s the level of access they could gain! This vulnerability is like a restaurant where anyone can change their reservation status from a table for one to a VIP table, all because the system doesn’t verify who is at the door. It’s a surprisingly sneaky flaw lurking in userlogin.jsp. If exploited, an attacker could easily elevate their privileges, allowing them to access sensitive data or even manipulate course content. This could lead to unauthorized changes, data leaks, or disruptions in the learning environment, which could be absolutely devastating for both educators and students.
