CVE-2022-36046
Unexpected server crash in Next.js version 12.2.3
In short
Next.js version 12.2.3 can crash unexpectedly when running on Node.js v15+ with certain server configurations, causing your web application to become unavailable.
Technical detail
An unhandled promise rejection in Next.js 12.2.3 triggers process termination when running with Node.js v15.0.0+ configured with strict unhandledRejection handling on next start or custom servers; shared server instances across requests are vulnerable, while Vercel deployments are unaffected due to isolated server contexts.
