Description
Impact
CSRF vulnerability allowing attackers to change the state of an order's adjustments if they hold its number, and the execution happens on a store administrator's computer.
Reproduction steps:
- Take an order's number.
- Log in as an administrator.
- Visit that order's adjustments section (Orders -> {Click on number} -> Adjustments) and check that its adjustments are finalized (closed padlock under the State column).
- On another tab, visit
{your_site_url}/admin/orders/{order_number}/adjustments/unfinalize. - Notice how the adjustments are unfinalized (open padlock), even if the previous was a
GETrequest which could have been linked from any other site. - Visit
{your_site_url}/admin/orders/{order_number}/adjustments/finalize. - Notice how the adjustments are again finalized.
That happened because both routes were handled as GET requests, which are skipped by Rails anti-forgery protection.
Patches
Users should upgrade to solidus_backend v3.1.6, v3.0.6, or v2.11.16, depending on the major and minor versions in use.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for solidus_backend, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update solidus_backend to 2.11.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-31000 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
