My understanding of the issue is that even if you don't use server components, you're still vulnerable.
Unless you're running a static html export - eg: not running the nextjs server, but serving through nginx or similar
Yeah, crucially it says
> If your app’s React code does not use a server, your app is not affected by this vulnerability. If your app does not use a framework, bundler, or bundler plugin that supports React Server Components, your app is not affected by this vulnerability.

So if you have a backend that supports RSC, even if you don't use it, you can still be vulnerable.
GP said they only shipped front ends but that can mean a lot.
