Fix Lack of Resources & Rate Limiting in Spiral
Spiral's high-performance RoadRunner core makes it a beast, but that speed is a liability if your endpoints are unprotected. Lack of rate limiting allows attackers to exhaust worker pools, spam expensive DB queries, or brute-force authentication. In a long-running PHP environment, resource exhaustion doesn't just slow down a request; it can choke the entire server daemon. You need to implement PSR-15 middleware to intercept and throttle malicious traffic before it hits your business logic.
The Vulnerable Pattern
namespace App\Controller;\n\nuse Spiral\Router\Annotation\Route;\n\nclass AuthController\n{\n #[Route(path: 'auth/login', name: 'login', methods: 'POST')]\n public function login(): array\n {\n // VULNERABLE: No throttling. An attacker can fire 10,000 requests per second\n // to brute-force credentials or exhaust worker threads.\n return ['status' => 'attempting login'];\n }\n}The Secure Implementation
The fix involves implementing a PSR-15 Middleware that acts as a gatekeeper. By using a fast-access storage layer like Redis, we track request counts per IP or User ID. If the threshold (e.g., 5 requests per minute) is exceeded, we return a HTTP 429 Too Many Requests status immediately, preventing the expensive controller logic and database drivers from ever being invoked. In Spiral, always ensure your rate-limiting state is stored in a shared cache (like Redis) rather than local memory to account for multiple RoadRunner workers.
namespace App\Middleware;\n\nuse Psr\Http\Message\ResponseInterface;\n\nclass RateLimitMiddleware implements \\Psr\\Http\\Server\\MiddlewareInterface\n{\n public function process($request, $handler): ResponseInterface\n {\n $ip = $request->getServerParams()['REMOTE_ADDR'];\n $key = "rate_limit:" . $ip;\n\n // Assume $this->cache is a Redis-backed Spiral Cache\n $attempts = (int)$this->cache->get($key) ?? 0;\n\n if ($attempts >= 5) {\n return new \\Nyholm\\Psr7\\Response(429, [], 'Too Many Requests');\n }\n\n $this->cache->set($key, $attempts + 1, 60);\n return $handler->handle($request);\n }\n}\n\n// Then apply to the Route:\n#[Route(path: 'auth/login', methods: 'POST', middleware: [RateLimitMiddleware::class])]\npublic function login() { ... }
