Fix Shadow API Exposure in Spiral

Shadow API exposure in Spiral occurs when the framework's auto-discovery and attribute-based routing mechanisms inadvertently publish internal logic or legacy endpoints to the public-facing gateway. In a high-performance PHP environment like Spiral, this often stems from over-reliance on the `#[Route]` attribute without accompanying guard middleware or explicit route grouping, creating an unmonitored attack surface.

The Vulnerable Pattern

namespace App\Controller;

use Spiral\Router\Annotation\Route;

class InternalSystemController { // Vulnerable: This route is automatically discovered and exposed publicly // without any authorization or network-level restrictions. #[Route(path: ‘/api/internal/config-dump’, name: ‘internal.config’, methods: ‘GET’)] public function getConfig(): array { return $_ENV; } }

The Secure Implementation

To mitigate Shadow APIs, you must enforce 'Security by Default'. 1. Stop relying on automated attribute discovery for sensitive modules; define these routes explicitly in a Bootloader. 2. Implement a 'Deny by Default' policy using Spiral's Guard component or RBAC. 3. Use Middleware to intercept requests based on IP allow-lists or internal tokens. 4. Audit the 'spiral/router' manifest regularly using terminal commands to list all registered routes and identify undocumented endpoints before an attacker does.

namespace App\Controller;

use Spiral\Router\Annotation\Route; use App\Middleware\InternalNetworkGuard;

class InternalSystemController { // Secure: Route is protected by specific middleware and restricted to internal scopes. #[Route( path: ‘/api/internal/config-dump’, name: ‘internal.config’, methods: ‘GET’, middleware: [InternalNetworkGuard::class] )] public function getConfig(): array { // Implement strict DTOs or filtered views instead of raw globals return [‘status’ => ‘active’, ‘version’ => ‘1.0.0’]; } }

// In your RoutesBootloader, ensure you are not using global wildcards // and instead segmenting your API versions and internal tools.
