Symfony2 logout CSRF protection: csrf_provider unrecognized
csrf-protection, logout, symfony
Solution
I've researched the Symfony's code and find that now `csrf_provider` option renamed to `csrf_token_generator`. Then I googled and found related issue on GitHub. So the problem in an unsynchronized documentation.
The final solution is:
configuration:
# app/config/security.yml
security:
# ...
firewalls:
# ...
your_firewall_name:
# ...
logout:
# ...
csrf_token_generator: your_csrf_provider # e.g. form.csrf_provider
twig template:
<a href="{{ logout_url('your_firewall_name') }}">Logout</a>
Note, that we're using `logout_url()` instead of `logout_path()` due to helper bug (it generates absolute path without `app_dev.php` suffix in dev environment). Theese twig helpers appends `%token_parameter%` to your logout URI, e.g. `http://example.com/app_dev.php/logout?_csrf_token=36wX6HYU2ASeZBQw_iwKcUDbplmFm4W7Ez-tMaavDNo`.
Hope this information will be helpful.
Problem
How can I protect the logout action? I read default configuration, and set ``` logout: csrf_parameter: _token csrf_provider: ~ intention: logout ``` but when I'm trying to clear cache the following error displayed: [Symfony\Component\Config\Definition\Exception\InvalidConfigurationException] Unrecognized options "csrf_provider" under "security.firewalls.main.logout" I'm using Symfony 2.4 + FOSUserBundle 1.3.
