The upstream advisory applies to self-hosted applications using the built-in Next.js Node.js server. Vercel-hosted deployments are not affected. A vulnerable dependency is actionable patch evidence, but it does not by itself prove the application uses the affected hosting model or that server-side request forgery is reachable.
Nasıl çalışır
FixVibe scopes the repo result to the `next` npm package and the affected release branches documented by the reviewed advisory. Exact resolved releases produce the strongest signal; supported dependency ranges are reported when they can resolve to an affected published release.
Etki yarıçapı
Under the advisory's self-hosting and routing conditions, crafted WebSocket upgrade handling can cause the server to proxy requests to unintended internal or external destinations. Practical exposure depends on the deployed server mode, origin reachability, routing configuration, outbound network policy, and destination reachability.

FixVibe repo scans look for high-confidence security patterns and dependency risk in source context. Reports identify the affected area and recommended fix.

Sağlam savunmalar
Upgrade to Next.js 15.5.16 or newer on the 13.x-15.x line, or 16.2.5 or newer on the 16.x line. Regenerate the active lockfile and rebuild self-hosted server artifacts. For self-hosted origins, review external rewrites, WebSocket handling, origin exposure, network segmentation, and egress controls; block unneeded WebSocket upgrades while rollout completes.
