Ignite Realtime Openfire allows remote authenticated users to cause a denial of service

CVE-2008-1728GHSA-x337-43mr-gg3h

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.igniterealtime.openfire:parent 3.5.0; org.igniterealtime.openfire:openfire 3.5.0), 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-2008-1728

Advisory: Ignite Realtime Openfire allows remote authenticated users to cause a denial of service
IDs: CVE-2008-1728, GHSA-x337-43mr-gg3h
Record: https://patchnext.com/advisories/cve-2008-1728 (revision 1, source checked 26 Oct 2026, 16:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.igniterealtime.openfire:parent 3.5.0; org.igniterealtime.openfire:openfire 3.5.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.igniterealtime.openfire:parent: affected < 3.5.0; fixed in 3.5.0
- Maven org.igniterealtime.openfire:openfire: affected < 3.5.0; fixed in 3.5.0

## Suggested inspection (read-only)
- Maven org.igniterealtime.openfire:parent: check the installed version with your package manager.
- Maven org.igniterealtime.openfire:openfire: 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.igniterealtime.openfire:parent, org.igniterealtime.openfire:openfire.
- 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-x337-43mr-gg3h (GitHub-reviewed advisory GHSA-x337-43mr-gg3h lists affected ranges: Maven org.igniterealtime.openfire:parent >=0 =0 <3.5.0)
