Laravel – CSRF Protection

CSRF refers to Cross Site Forgery attacks on web applications. CSRF attacks are the unauthorized activities which the authenticated users of the system perform. As such, many web applications are prone to these attacks.

Laravel offers CSRF protection in the following way −

Laravel includes an in built CSRF plug-in, that generates tokens for each active user session. These tokens verify that the operations or requests are sent by the concerned authenticated user.


The implementation of CSRF protection in Laravel is discussed in detail in this section. The following points are notable before proceeding further on CSRF protection −

  • CSRF is implemented within HTML forms declared inside the web applications. You have to include a hidden validated CSRF token in the form, so that the CSRF protection middleware of Laravel can validate the request. The syntax is shown below −
<form method = "POST" action="/login">
   {{ csrf_field() }}
  • You can conveniently build JavaScript driven applications using JavaScript HTTP library, as this includes CSRF token to every outgoing request.
  • The file namely resources/assets/js/bootstrap.js registers all the tokens for Laravel applications and includes meta tag which stores csrf-token with Axios HTTP library.
