Wafris for Laravel

Latest Version on Packagist GitHub Tests Action Status GitHub Code Style Action Status Total Downloads

Wafris is an open-source Web Application Firewall (WAF) that runs within Laravel (and other frameworks) powered by Redis.

Paired with Wafris Hub, you can create rules to block malicious traffic from hitting your application.

Rules and Graph

Rules like:

  • Block IP addresses (IPv6 and IPv4) from making requests
  • Block on hosts, paths, user agents, parameters, and methods
  • Rate limit (throttle) requests
  • Visualize inbound traffic and requests

Installation

1. Connect on Wafris Hub

Go to https://wafris.org/hub to create a new account and follow the instructions to link your Redis instance.

Note: In Step 3, you'll use this same Redis URL in your app configuration.

2. Install this library via Composer

composer require wafris/laravel-wafris

3. Publish and configure Wafris

You can publish the config file with:

php artisan vendor:publish --tag="wafris-config"

We recommend creating a separate Redis configuration for Wafris. That can be done in config/database.php with a new entry like this:

'redis' => [

    'client' => env('REDIS_CLIENT', 'predis'), // Make sure to set your Redis client to predis

    'options' => [
        ...
    ],

    'default' => [
        ...
    ],

    'cache' => [
        ...
    ],

    'wafris' => [
        'url' => env('REDIS_URL'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'username' => env('REDIS_USERNAME'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', '6379'),
        'database' => env('REDIS_CACHE_DB', '3'),
        'read_write_timeout' => 1, // Timeout in seconds
    ],

],

Usage

Add the Wafris\AllowRequestMiddleware middleware to routes that you want to have protected by Wafris.

Protecting all routes

To protect all routes in your Laravel application, add the Wafris\AllowRequestMiddleware globally.

Laravel 11

Starting in Laravel 11, middleware are registered in bootstrap/app.php. Add the following line in the withMiddleware section of that file:

Application::configure(basePath: dirname(__DIR__))
    // ...
    ->withMiddleware(function (Middleware $middleware) {
        // ... other middleware
        $middleware->append(\Wafris\AllowRequestMiddleware::class);
    });

Laravel 10

To protect all routes in your Laravel application, add Wafris\AllowRequestMiddleware to the $middleware property of your app/Http/Kernel.php class.

// app/Http/Kernel.php

/**
 * The application's global HTTP middleware stack.
 *
 * These middleware are run during every request to your application.
 *
 * @var array<int, class-string|string>
 */
protected $middleware = [
    // \App\Http\Middleware\TrustHosts::class,
    \App\Http\Middleware\TrustProxies::class,
    \Illuminate\Http\Middleware\HandleCors::class,
    \App\Http\Middleware\PreventRequestsDuringMaintenance::class,
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
    \App\Http\Middleware\TrimStrings::class,
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    \Wafris\AllowRequestMiddleware::class,
];

Protecting specific middleware groups

To protect specific middleware groups, such as the web or api groups, add Wafris\AllowRequestMiddleware to each desired middleware group in your app/Http/Kernel.php class.

// app/Http/Kernel.php

/**
 * The application's route middleware groups.
 *
 * @var array<string, array<int, class-string|string>>
 */
protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        \Wafris\AllowRequestMiddleware::class,
    ],

    'api' => [
        // \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
        \Illuminate\Routing\Middleware\ThrottleRequests::class.':api',
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        \Wafris\AllowRequestMiddleware::class,
    ],
];

Protecting individual routes

Use the Wafris\AllowRequestMiddleware middleware when defining your route.

// routes/web.php

Route::get('/signup', function () {
    // ...
})->middleware(\Wafris\AllowRequestMiddleware::class);

Testing
