# Patch Next advisory brief: CVE-2021-29052

Advisory: Liferay Portal and Liferay DXP Fails to Check Permissions
IDs: CVE-2021-29052, GHSA-pr7v-qv65-rp9m
Record: https://patchnext.com/advisories/cve-2021-29052 (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 4.3)
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 7.3.10.fp1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay.portal:release.portal.bom: affected >= 7.3.0, <= 7.3.5
- Maven com.liferay.portal:release.dxp.bom: affected < 7.3.10.fp1; fixed in 7.3.10.fp1

## 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
- Verified: https://github.com/advisories/GHSA-pr7v-qv65-rp9m (GitHub-reviewed advisory GHSA-pr7v-qv65-rp9m lists affected ranges: Maven com.liferay.portal:release.portal.bom >=7.3.0 =0 <7.3.10.fp1)
