CVE-2021-41274 | Authentication Bypass by CSRF Weakness

Exp

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.

Base score Version Severity Vector Exploitability Impact Score source
9.3 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.

Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
