Student enrollment disclosure via unchecked REST route
Published Sep 2, 2026 · Updated Sep 2, 2026
Information exposure in MasterStudy LMS before 3.7.46 allows remote attackers to read registered users’ course and progress data. The student-courses REST route returns per-student enrollment and learning-progress records without performing an authorization check on the requested user. No authentication or user interaction is required, and the consequence is limited to disclosure of enrolled courses and progress.
