User-to-Administrator escalation via broken authorization check
Published Apr 18, 2026 · Updated Apr 18, 2026
Incorrect authorization in Lee Peuker's Movary before 0.71.1 allows remote authenticated users to create administrator accounts. The /settings/users routes omit admin-only middleware, while UserController combines failed authentication and non-admin status with AND, allowing logged-in non-admin requests. Any user with a valid session can enumerate user identifiers, email addresses, and admin status, then create a new account with administrative privileges.
