Inngest SDK Exposes Environment Variables via Unhandled HTTP Methods

Inngest TypeScript SDK versions 3.22.0 through 3.53.1 expose environment variables via the serve() handler on unhandled HTTP methods, allowing unauthenticated remote attackers to exfiltrate environment variables from the host process via `PATCH`, `OPTIONS`, or `DELETE` requests to the `serve()` HTTP handler.
