• Accept base64_urlsafe CSRF tokens to make forward compatible.

  Base64 strict-encoded CSRF tokens are not inherently websafe, which makes
  them difficult to deal with. For example, the common practice of sending
  the CSRF token to a browser in a client-readable cookie does not work properly
  out of the box: the value has to be url-encoded and decoded to survive transport.

  In this version, we generate Base64 urlsafe-encoded CSRF tokens, which are inherently
  safe to transport. Validation accepts both urlsafe tokens, and strict-encoded
  tokens for backwards compatibility.

  How the tokes are encoded is controllr by the action_controller.urlsafe_csrf_tokens
  config.

  In Rails 5.2.5, the CSRF token format was accidentally changed to urlsafe-encoded.

  Atention: If you already upgraded your application to 5.2.5, set the config
  urlsafe_csrf_tokens to true, otherwise your form submission will start to fail
  during the deploy of this new version.

  Rails.application.config.action_controller.urlsafe_csrf_tokens = true

  If you are upgrading from 5.2.4.x, you don't need to change this configuration.
