Magento 2 Community Edition XSS Vulnerability

CVE-2019-8142GHSA-298q-wv2h-v5vw

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (magento/community-edition 2.3.2-p1, 2.2.10), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2019-8142

Advisory: Magento 2 Community Edition XSS Vulnerability
IDs: CVE-2019-8142, GHSA-298q-wv2h-v5vw
Record: https://patchnext.com/advisories/cve-2019-8142 (revision 1, source checked 26 Oct 2026, 14:15 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: magento/community-edition 2.3.2-p1, 2.2.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist magento/community-edition: affected >= 2.2.0, < 2.2.10; >= 2.3.0, < 2.3.2-p1; fixed in 2.3.2-p1, 2.2.10

## Suggested inspection (read-only)
- Packagist magento/community-edition: 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 magento/community-edition.
- 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-298q-wv2h-v5vw (GitHub-reviewed advisory GHSA-298q-wv2h-v5vw lists affected ranges: Packagist magento/community-edition >=2.2.0 =2.3.0 <2.3.2-p1)
