Liferay Portal is vulnerable to XSS attack through its Style Book theme

CVE-2025-43774GHSA-qgj5-4qvg-2f8c

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (com.liferay:com.liferay.frontend.taglib.clay 15.2.1), 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-2025-43774

Advisory: Liferay Portal is vulnerable to XSS attack through its Style Book theme
IDs: CVE-2025-43774, GHSA-qgj5-4qvg-2f8c
Record: https://patchnext.com/advisories/cve-2025-43774 (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: Low (CVSS 2.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.liferay:com.liferay.frontend.taglib.clay 15.2.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay:com.liferay.frontend.taglib.clay: affected < 15.2.1; fixed in 15.2.1

## Suggested inspection (read-only)
- Maven com.liferay:com.liferay.frontend.taglib.clay: 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:com.liferay.frontend.taglib.clay.
- 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-qgj5-4qvg-2f8c (GitHub-reviewed advisory GHSA-qgj5-4qvg-2f8c lists affected ranges: Maven com.liferay:com.liferay.frontend.taglib.clay >=0 <15.2.1)

Commands are suggestions: review each one before running it.
