Technical details
The PATCH /private/role_bindings/:binding_id endpoint validates only that a new role's priority rank does not exceed the caller's rank, but fails to check the existing binding's role rank—a check that the DELETE handler correctly performs. An authenticated org_admin (rank 90) can therefore demote an org_super_admin (rank 95) to org_member (rank 75). Additionally, the prevent_last_super_admin_binding_delete database trigger fires only on DELETE operations, not UPDATE, allowing complete removal of all super_admin bindings via PATCH requests.
