-  message: >-
-    Checks for dangerous permitted attributes that can lead to mass assignment vulnerabilities.
-    Query parameters allowed using permit
-    and attr_accessible are checked for allowance of dangerous attributes admin, banned,
-    role, and account_id. Also checks for usages of
-    params.permit!, which allows everything. Fix: don't allow admin, banned, role,
-    and account_id using permit or attr_accessible.
