Narayana deadlock via multiple join requests sent to LRA Coordinator

CVE-2024-8447GHSA-qq9f-q439-2574

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.jboss.narayana.rts:lra-coordinator-jar 7.1.0.Final), 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.

Source description

As published by the source; long descriptions are shortened.

A security issue was discovered in the LRA Coordinator component of Narayana. When Cancel is called in LRA, an execution time of approximately 2 seconds occurs. If Join is called with the same LRA ID within that timeframe, the application may crash or hang indefinitely, leading to a denial of service.

# Patch Next advisory brief: CVE-2024-8447

Advisory: Narayana deadlock via multiple join requests sent to LRA Coordinator
IDs: CVE-2024-8447, GHSA-qq9f-q439-2574
Record: https://patchnext.com/advisories/cve-2024-8447 (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: org.jboss.narayana.rts:lra-coordinator-jar 7.1.0.Final. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.jboss.narayana.rts:lra-coordinator-jar: affected < 7.1.0.Final; fixed in 7.1.0.Final

## Suggested inspection (read-only)
- Maven org.jboss.narayana.rts:lra-coordinator-jar: 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 org.jboss.narayana.rts:lra-coordinator-jar.
- 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-qq9f-q439-2574 (GitHub-reviewed advisory GHSA-qq9f-q439-2574 lists affected ranges: Maven org.jboss.narayana.rts:lra-coordinator-jar >=0 <7.1.0.Final)

Commands are suggestions: review each one before running it.
