CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
        $last = function ($schema, $query, $context, $vars) {
            return GraphQL::executeQuery($schema, $query, null, $context, $vars);
        };
