Critical severity vulnerability was found in bundler solidus_auth_devise (RubyGems) .


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.


Users should promptly update to solidus_auth_devise version 2.5.4.


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.



We’d like to thank vampire000 for reporting this issue.
