Rails 4 ActionController :: InvalidAuthenticityToken с несколькими подобластями

Question

Прежде чем я скажу, что я ищу google и много сообщений здесь, в Stackoverflow, но ничто не могло дать решение для моей проблемы. для этого я создаю новый пост.

Я создаю приложение с двумя поддоменами: account.psantos.dev и app.psantos.dev.

В: config/initializers/session_store.rb у меня есть:

Rails.application.config.session_store :cookie_store, key: '_psantos.co.ao_session', domain: 'psantos.dev' 

И у меня есть следующие структуры папок:

- app
-- controllers
--- app1
---- welcome_controller.rb
--- account
---- welcome_controller.rb
--views
--- layout
---- app1.html.erb
---- account.html.erb
--- app1
---- welcome
----- index.html.erb
--- account
---- welcome
----- index.html.erb

на: app/views/layout/app1.html.erb (http://app1.psantos.dev) У меня есть следующие строки:

<li><%= "Logout", account_sign_out_url, method: :delete %></li> 

Когда я нажимаю эту ссылку (это перейдет к: http://account.psantos.dev), я получил следующее сообщение об ошибке:
ActionController::InvalidAuthenticityToken at /sign_out ActionController::InvalidAuthenticityToken

на обоих файлах макета (app1.html.erb и account.html.erb) Я эту строку перед < \ HEAD> тег:

<%= csrf_meta_tags %> 

как я могу решить эту проблему?

Update: отношение журнала

There is an vulnerability in jquery-ujs and jquery-rails that can be used to bypass CSP protections and allows attackers to send CSRF tokens to attacker domains. This vulnerability has been assigned the CVE identifier CVE-2015-1840. Versions Affected: All. Not affected: Applications which don't use jquery-ujs or jquery-rails. Fixed Versions: jquery-rails versions 4.0.4 and 3.1.3 and jquery-ujs 1.0.4. Impact ------ In the scenario where an attacker might be able to control the href attribute of an anchor tag or the action attribute of a form tag that will trigger a POST action, the attacker can set the href or action to " https://attacker.com " (note the leading space) that will be passed to JQuery, who will see this as a same origin request, and send the user's CSRF token to the attacker domain.
