I'm hearing about it like crazy because I deployed around 100 Next frontends in that time period. I didn't use server components though so I'm not affected.

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.

https://react.dev/blog/2025/12/03/critical-security-vulnerab...

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.

		They might be referring to another Vercel vulnerability that allowed anyone to bypass their auth with relative ease due to poor engineering practices: https://nvd.nist.gov/vuln/detail/CVE-2025-29927 That plus the most recent react one, and you have a culture that does not care for their customers but rather chasing fads to help greedy careers.
