These wiz.io blog posts should be banned from HN; AFAICT, they're AI generated. Here's the original post with the details: https://react.dev/blog/2025/12/03/critical-security-vulnerab... - the vulnerability was not found by a Wiz employee at all, and the Wiz article (unlike the react.dev article) does not provide any meaningful technical information.

The important part to know:

- Even if your app does not implement any React Server Function endpoints it may still be vulnerable if your app supports React Server Components.

- The vulnerability is present in versions 19.0, 19.1.0, 19.1.1, and 19.2.0 of: react-server-dom-webpack, react-server-dom-parcel, react-server-dom-turbopack

- Some React frameworks and bundlers depended on, had peer dependencies for, or included the vulnerable React packages. The following React frameworks & bundlers are affected: next, react-router, waku, @parcel/rsc, @vitejs/plugin-rsc, and rwsdk.

What is the "tell"? I'm not saying they are or aren't, but... people say this about literally everything now and it's typically some flimsy reasoning like "they used a bullet point". I don't see anything in particular that makes me think ai over a standard template some junior fills out.

>the vulnerability was not found by a Wiz employee at all

I've re-read the Wiz article a few times. Maybe I'm just dumb, but where did Wiz claim to have found this vulnerability?

When I saw "WIZ Research - Critical Vulnerabilities in React and Next.js" on the big image banner, I immediately thought that Wiz found the vulnerability.

When Reuters has an article that says "Reuters Business - Interest rates going up", do you think Reuters made the interest rates go up themselves or that they are reporting on the interest rates?
