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.

There is some value:

> The vulnerability exists in the default configuration of affected applications

Can be inferred from the react blog but isn't really explicit

> According to Wiz data, 39% of cloud environments have instances vulnerable to CVE-2025-55182 and/or CVE-2025-66478.

Numbers!
