EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2022-31000 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,567 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-31000 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-31000. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-31000 in your dependencies?
O3 Security finds CVE-2022-31000 across RubyGems dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
