How do I fix GHSA-mfjw-x4q4-69p9?

Update org.igniterealtime.openfire:parent to 4.5.0-beta or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mfjw-x4q4-69p9 is resolved across your whole dependency graph.

How do I detect GHSA-mfjw-x4q4-69p9 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.igniterealtime.openfire:parent, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-mfjw-x4q4-69p9 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is GHSA-mfjw-x4q4-69p9 actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-mfjw-x4q4-69p9, including 1 in-the-wild exploitation observed on GitHub and other sources.
