CVE-2021-41275 Information

Description

spree_auth_devise is an open source library which provides authentication and authorization services for use with the Spree storefront framework by using an underlying Devise authentication framework. In affected versions spree_auth_devise is subject to a 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 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). Users are advised to update their spree_auth_devise gem. For users unable to update it may be possible to change your strategy to :exception. Please see the linked GHSA for more workaround details.

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. Thanks @waiting-for-dev for reporting and providing a patch ?
