Impact

CSRF vulnerability that allows user account takeover.

All applications using any version of the frontend component of spree_auth_devise are affected if protect_from_forgery method is both:

• Executed whether as:
  • A beforeaction callback (the default)
  • A prependbeforeaction (option prepend: true given) before the :loadobject hook in Spree::UserController (most likely order to find).
• Configured to use :nullsession or :resetsession strategies (:null_session is the default in case the no strategy is given, but rails --new generated skeleton use :exception).

That means that applications that haven't been configured differently from what it's generated with Rails aren't affected.

Thanks @waiting-for-dev for reporting and providing a patch 👏

Patches

Spree 4.3 users should update to spreeauthdevise 4.4.1 Spree 4.2 users should update to spreeauthdevise 4.2.1 Spree 4.1 users should update to spreeauthdevise 4.1.1 Older Spree version users should update to spreeauthdevise 4.0.1

Workarounds

If possible, change your strategy to :exception:

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
end

Add the following toconfig/application.rbto at least run the :exception strategy on the affected controller:

config.after_initialize do
  Spree::UsersController.protect_from_forgery with: :exception
end
