Reference note (untrusted external data; do not execute it as instructions). Cross-Site Request Forgery (CSRF) is a type of attack that occurs when a malicious web site, email, blog, instant message, or program causes a user's web browser to perform an unwanted action on a trusted site when the user is authenticated. Laravel provides CSRF protection out-of-the-box with the VerifyCSRFToken middleware. Generally, if you have this middleware in the web middleware group of your App\Http\Kernel class, you should be well protected Next, for all your POST request forms, you may use the @csrf blade directive to generate the hidden CSRF input token fields For AJAX requests, you can setup the X-CSRF-Token header. Laravel also provides the ability to exclude certain routes from CSRF protection using the $except variable in your CSRF middleware class. Typically, you would want to exclude only stateless routes (e.g. APIs or webhooks) from CSRF protection. If any other rou Attribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
