Laravel – CSRF Protection

 

 

CSRF stands for Cross Site Forgery attacks, Which is found on web http. CSRF attacks is one of the unauthorized activities.

Laravel provides the CSRF protection in the following options

Laravel having the inbuilt CSRF plug-in, which is generates the tokens for each user sessions . This tokens verify the request which is sent by the authenticated user.

Implementation :

Lets the discuss , how to implements this CSRF features in laravel .

CSRF implements in as hidden field in form html , so that CSRF protection middleware of laravel can validate this request , which is sent by users

 

<form name="form_name" method = "POST" action="/profile">
{{ csrf_field() }}

</form>

All the tokens for Laravel applications are registers in the folder resources/assets/js/bootstrap.js

Form without CSRF token :

This is below form , which is having without CSRF token .

<form name="name" method="post">
<label> Email </label>
<input type = "text" name = "email"/>
<br/>
<label> Message </label> <input type="text" name = "message"/>
<input type = ”submit” name = ”submit” value = ”submit”>
</form>

When we submit this form to our controller method , It is not secure and it may contains prone to various attacks

Form with CSRF token :

This is below form which is contains the CRSF tokens as in hiiden input tag.

 

<form method = "post" name="csrf">
{{ csrf_field() }}
<label> Email </label>
<input type = "text" name = "email"/>
<br/>
<label> Message </label>
<input type = "text" name = "message"/>
<input type = ”submit” name = "submit" value = "submit">
</form>

 

I will receive the response as in json format with token :

 

{
"token": "ghfleifxDSUYEW9WE67877CXNVFJMN",
"name": "outsource2global",
"email": "alexawork113@gmail.com"
}
