by using a random token injected in the form and using the session to store and control the token
submitted by the user.
When using the FrameworkBundle, this protection can be enabled or disabled with the
configuration. If the configuration is not specified, by default, the mechanism is enabled as
long as the session is enabled.
In a recent change in the way the configuration is loaded, the default behavior has been dropped
and, as a result, the CSRF protection is not enabled in form when not explicitly enabled, which
makes the application sensible to CSRF attacks.");
