XSS (Cross-Site Scripting) Protection in Laravel

Imagine you have a register and comment section in your laravel application, in this section anyone can type a comment and register with some script tag and other hacking script tags our application does not check the script and the tags using the scripts anyone can store the script in our database, This term is called XSS attack.

If you have e-Commerce and blog submission sites, anyone can drop his script on login and register, So we will prevent this by using middleware and removing all the tags and script whenever the user can register and post a comment.

Create a Middleware

php artisan make:middleware Xss



namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class Xss
     * Handle an incoming request.
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next
     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
    public function handle(Request $request, Closure $next)
        $input = $request->all();
        array_walk_recursive($input, function(&$input){
            $input = strip_tags($input);
        return $next($request);

Update Kernel File :

We need to update your Kernel.php file inside the same App/Http/Middleware directory where we need to add the middleware name as shown below.

      'XSS' => \App\Http\Middleware\Xss::class,



#XSS Protection
Route::group(['middleware' => 'XSS'], function(){

Route::post('/store-register', [UserController::class, 'userRegiter'])->name('store.register');
