CVE-2021-41274 — Vulnerability in solidus_auth_devise — CVE Details

### 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`: ```ruby 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: ```ruby 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`.
