# Patch Next advisory brief: CVE-2026-25522

Advisory: Craft Commerce has Stored XSS in Shipping Zone (Name & Description) Fields Leading to Potential Privilege Escalation
IDs: CVE-2026-25522, GHSA-h9r9-2pxg-cx9m
Record: https://patchnext.com/advisories/cve-2026-25522 (revision 1, source checked 26 Oct 2026, 14:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: craftcms/commerce 5.5.2, 4.10.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist craftcms/commerce: affected >= 5.0.0-RC1, <= 5.5.1; >= 4.0.0-RC1, <= 4.10.0; fixed in 4.10.1, 5.5.2

## Suggested inspection (read-only)
- Packagist craftcms/commerce: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on craftcms/commerce.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-h9r9-2pxg-cx9m (GitHub-reviewed advisory GHSA-h9r9-2pxg-cx9m lists affected ranges: Packagist craftcms/commerce >=5.0.0-RC1 =4.0.0-RC1 <=4.10.0)
