# Patch Next advisory brief: CVE-2025-43734

Advisory: Liferay Portal 7.4.0 and Liferay DXP have a reflected cross-site scripting (XSS) vulnerability
IDs: CVE-2025-43734, GHSA-m5c7-5gv3-hcpf
Record: https://patchnext.com/advisories/cve-2025-43734 (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 5.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: com.liferay.portal:release.dxp.bom 2025.q1.11, 2024.q1.17; com.liferay:com.liferay.frontend.taglib.clay 15.2.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay.portal:release.portal.bom: affected >= 7.4.0, <= 7.4.3.132
- Maven com.liferay.portal:release.dxp.bom: affected >= 2024.q4.0, <= 2024.q4.7; >= 2024.q3.0, <= 2024.q3.13; >= 2024.q2.0, <= 2024.q2.13; >= 2024.q1.0, <= 2024.q1.16; >= 2025.q1.0, <= 2025.q1.10; <= 7.4.13.u92; fixed in 2025.q1.11, 2024.q1.17
- Maven com.liferay:com.liferay.frontend.taglib.clay: affected < 15.2.2; fixed in 15.2.2

## Suggested inspection (read-only)
- Maven com.liferay.portal:release.portal.bom: check the installed version with your package manager.
- Maven com.liferay.portal:release.dxp.bom: check the installed version with your package manager.
- Maven com.liferay:com.liferay.frontend.taglib.clay: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on com.liferay.portal:release.portal.bom, com.liferay.portal:release.dxp.bom, 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.
