Next.js is a React framework that can provide building blocks to create web applications. All of the following must be true to be affected by this CVE: Next.js version 12.2.3, Node.js version above v15.0.0 being used with strict `unhandledRejection` exiting AND using next start or a [custom server](https://nextjs.org/docs/advanced-features/custom-server). Deployments on Vercel ([vercel.com](https://vercel.com/)) are not affected along with similar environments where `next-server` isn't being shared across requests.

Next.js is a React framework. In versions of Next.js prior to 12.0.5 or 11.1.3, invalid or malformed URLs could lead to a server crash. In order to be affected by this issue, the deployment must use Next.js versions above 11.1.0 and below 12.0.5, Node.js above 15.0.0, and next start or a custom server. Deployments on Vercel are not affected, along with similar environments where invalid requests are filtered before reaching Next.js. Versions 12.0.5 and 11.1.3 contain patches for this issue.
