- Also known as: GHSA-XM34-V85H-9PG2
- Severity: CVSS 9.3 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N
- Known exploited (CISA KEV): no
- Fixed in: 2.5.4
- Published: 2021-11-17 · Updated: 2024-08-04

## Affected

- solidusio solidus\_auth\_devise: from 1.0.0, fixed in 2.5.4
- solidus\_auth\_devise (RubyGems): from 1.0.0, fixed in 2.5.4

## Description

solidus_auth_devise provides authentication services for the Solidus webstore framework, using the Devise gem. In affected versions solidus_auth_devise is subject to a 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) or 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 should promptly update to `solidus_auth_devise` version `2.5.4`. Users unable to update should if possible, change their strategy to `:exception`. Please see the linked GHSA for more workaround details.
