CVE-2026-75460Public exploitNetwork attack vector

Authenticated account disclosure via controllable role filter

Published Aug 31, 2026 · Updated Sep 1, 2026

Improper authorization in XueZhiSi Open Source Exam System 3.9.0 and earlier allows remote authenticated users to enumerate accounts. The teacher-end POST /api/teacher/user/page/list endpoint uses the caller-controlled UserPageRequestVM.role value as its user-list filter without enforcing the session's allowed role scope. Teacher-role credentials are required, and successful exploitation exposes account records across roles without changing data or interrupting service.
