SurrealDB from 3.1.0 before 3.3.0 contains an authorization bypass vulnerability that allows authenticated users to delete protected graph edges by triggering a REFERENCE ON DELETE CASCADE. Attackers with delete permission on a referenced table can delete a record whose cascade disables permission checks for edge cleanup, erasing edges despite the edge table's PERMISSIONS FOR delete clause.
