Student statistics disclosure via unchecked REST route
Published Sep 2, 2026 · Updated Sep 2, 2026
Information exposure in StylemixThemes MasterStudy LMS before 3.7.46 allows remote attackers to read registered students' learning statistics. The student/stats REST route returns course counts, points, certificates, and quiz and assignment totals for a supplied registered user without performing an authorization check. No authentication is required, and the consequence is limited to disclosure of those learning statistics; modification of student records is not reported.
