  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.");
