Technical details
An incorrect capability check in Moodle's grade web service (core_grades: get_gradable_users) allows authenticated students to bypass access controls. The vulnerability requires network access and student authentication; an attacker with valid student credentials can enumerate and access profile information of peer students enrolled in the same course. The fix involves improving the capability check logic as evidenced by commit MDL-89381.
