# Patch Next advisory brief: CVE-2022-42118

Advisory: Liferay Portal and Liferay DXP Vulnerable to XSS via the Portal Search Module
IDs: CVE-2022-42118, GHSA-mr77-4pm4-x9vm
Record: https://patchnext.com/advisories/cve-2022-42118 (revision 1, source checked 26 Oct 2026, 16:39 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: com.liferay.portal:release.dxp.bom 7.2.10.fp15, 7.1.10.fp27; com.liferay:com.liferay.portal.search.web 6.0.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay.portal:release.dxp.bom: affected >= 7.1.0, < 7.1.10.fp27; >= 7.2.0, < 7.2.10.fp15; fixed in 7.2.10.fp15, 7.1.10.fp27
- Maven com.liferay:com.liferay.portal.search.web: affected < 6.0.12; fixed in 6.0.12

## Suggested inspection (read-only)
- Maven com.liferay.portal:release.dxp.bom: check the installed version with your package manager.
- Maven com.liferay:com.liferay.portal.search.web: 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 com.liferay.portal:release.dxp.bom, com.liferay:com.liferay.portal.search.web.
- 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-mr77-4pm4-x9vm (GitHub-reviewed advisory GHSA-mr77-4pm4-x9vm lists affected ranges: Maven com.liferay:com.liferay.portal.search.web >=0 =7.1.0 =7.2.0 <7.2.10.fp15)
