- CVE-2025-66581Medium
Frappe Learning Management System (LMS) prior to 2.41.0 has a flaw in server-side authorization logic that allowed authenticated users to perform actions beyond their assigned roles across multiple features. Because affected endpoints relied on client-side or UI-level checks instead of enforcing permissions on the server, users with low-privileged roles (such as students) could perform operations intended only for instructors or administrators via directly using the APIs. This vulnerability is fixed in 2.41.0.
