Steps to reproduce:

1- Login to your account via Login page 2- Click on CSRF.html that attached. After that, you will redirect to a new page an see the error, the user after clicking on this file log out from account.

You can see in the CSRF file there isn't any token, but if you place a vaid CSRF token from the source page, this attack will be successful too.
