# Patch Next advisory brief: CVE-2025-43738

Advisory: Liferay Portal Reflected Cross-Site Scripting Vulnerability in displayType Parameter
IDs: CVE-2025-43738, GHSA-cwgh-r52j-xh6c
Record: https://patchnext.com/advisories/cve-2025-43738 (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: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay:com.liferay.expando.web: affected <= 5.0.59

## Suggested inspection (read-only)
- Maven com.liferay:com.liferay.expando.web: 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:com.liferay.expando.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-cwgh-r52j-xh6c (GitHub-reviewed advisory GHSA-cwgh-r52j-xh6c lists affected ranges: Maven com.liferay:com.liferay.expando.web >=0 <=5.0.59)

Commands are suggestions: review each one before running it.
