GHSA-xm34-v85h-9pg2

Impact

CSRF vulnerability that allows user account takeover.

All applications using any version of the frontend component of solidus_auth_devise are affected if protect_from_forgery method is both: - Executed whether as: - A before_action callback (the default) - A prepend_before_action (option prepend: true given) before the :load_object hook in Spree::UserController (most likely order to find). - Configured to use :null_session or :reset_session 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.

Patches

Users should promptly update to solidus_auth_devise version 2.5.4.

Workarounds

A couple of options:

• If possible, change your strategy to :exception:

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

• Add the following to config/application.rb to at least run the :exception strategy on the affected controller:

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

• We've also released new Solidus versions monkey patching solidus_auth_devise with the quick fix. Those versions are v3.1.3, v.3.0.3 & v2.11.12. See GHSA-5629-8855-gf4g for details.
