CVE-2025-65669Public exploitNetwork attack vector

Course deletion via unchecked student request

Published Nov 26, 2025 · Updated Jul 5, 2026

Missing authorization in ClassroomIO 0.1.13 allows remote authenticated users to delete published courses from the Explore page. The Explore page exposes its Delete Course action to student accounts, while the server-side deletion endpoint performs no role or permission validation before removing a course. A student account and published course are required, and exploitation removes administrator-created learning content and interrupts access to it.
