# Patch Next advisory brief: CVE-2021-33331

Advisory: Liferay Portal and Liferay DXP Allows Arbitrary Redirect of Users to External URLs
IDs: CVE-2021-33331, GHSA-mj8w-h522-jwm8
Record: https://patchnext.com/advisories/cve-2021-33331 (revision 1, source checked 26 Oct 2026, 16:36 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: Partial vendor fix; fixed versions by package: com.liferay.portal:release.dxp.bom 7.2.10.fp8, 7.1.10.fp19, 7.0.10.fp94. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay.portal:release.portal.bom: affected >= 7.0.0, <= 7.3.1
- Maven com.liferay.portal:release.dxp.bom: affected >= 7.0.10.fp0, < 7.0.10.fp94; >= 7.1.0, < 7.1.10.fp19; >= 7.2.0, < 7.2.10.fp8; fixed in 7.1.10.fp19, 7.0.10.fp94, 7.2.10.fp8

## 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.

## 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.
- 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
