• CVE-2021-29043: 0.74% estimated exploitation activity in the next 30 days; percentile 54.58 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

The Portal Store module in Liferay Portal 7.0.0 through 7.3.5, and Liferay DXP 7.0 before fix pack 97, 7.1 before fix pack 21, 7.2 before fix pack 10 and 7.3 before fix pack 1 does not obfuscate the S3 store's proxy password, which allows attackers to steal the proxy password via man-in-the-middle attacks or shoulder surfing.

# Patch Next advisory brief: CVE-2021-29043

Advisory: Liferay Portal and Liferay DXP May Reveal S3 Store's Proxy Password
IDs: CVE-2021-29043, GHSA-xx2h-2hf5-v7vv
Record: https://patchnext.com/advisories/cve-2021-29043 (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 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.liferay.portal:release.portal.bom 7.3.6; com.liferay.portal:release.dxp.bom 7.3.10.fp1, 7.2.10.fp10, 7.1.10.fp21, 7.0.10.fp97. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay.portal:release.portal.bom: affected >= 7.0.0, <= 7.3.5; fixed in 7.3.6
- Maven com.liferay.portal:release.dxp.bom: affected < 7.0.10.fp97; >= 7.1.0, < 7.1.10.fp21; >= 7.2.0, < 7.2.10.fp10; >= 7.3.0, < 7.3.10.fp1; fixed in 7.2.10.fp10, 7.1.10.fp21, 7.0.10.fp97, 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
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.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.
