Same for Netlify: https://www.netlify.com/changelog/2025-12-03-react-security-...
and Deno Deploy/Subhosting: https://deno.com/blog/react-server-functions-rce
We collaborated with many industry partners to proactively deploy mitigations due to the severity of the issue.
We still strongly recommend everyone to upgrade their Next, React, and other React meta-frameworks (peer)dependencies immediately.
