Basically, JavaScript should not be running on servers.

Vulnerabilities caused by shoddy JS are a lot more impactful to a server since multiple users will be served by the same runtime instance.

It's not JavaScript by itself. It's unsafe coding practices that blend production and development code.

The bug here is in the hot reloading code. It should not be enabled anywhere but on developers' machines.

Not entirely true. The bug is also in the dev server, but primarily the exploitable vulnerability is in apps built for production.
