Liferay Portal Path Traversal Vulnerability via the Hypermedia REST APIs Module

CVE-2022-28981GHSA-5j86-vmpx-42pc

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (com.liferay:com.liferay.headless.discovery.web 4.0.12), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2022-28981

Advisory: Liferay Portal Path Traversal Vulnerability via the Hypermedia REST APIs Module
IDs: CVE-2022-28981, GHSA-5j86-vmpx-42pc
Record: https://patchnext.com/advisories/cve-2022-28981 (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: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.liferay:com.liferay.headless.discovery.web 4.0.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.liferay:com.liferay.headless.discovery.web: affected < 4.0.12; fixed in 4.0.12

## Suggested inspection (read-only)
- Maven com.liferay:com.liferay.headless.discovery.web: 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:com.liferay.headless.discovery.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-5j86-vmpx-42pc (GitHub-reviewed advisory GHSA-5j86-vmpx-42pc lists affected ranges: Maven com.liferay:com.liferay.headless.discovery.web >=0 <4.0.12)

Commands are suggestions: review each one before running it.
