CVE-2022-36046Network attack vector

Authenticated server crash via unhandled request rejection

Published Aug 31, 2022 · Updated Apr 23, 2025

Denial of service in Vercel Next.js 12.2.3 allows remote authenticated users to crash a shared server process with specific requests. The server request path permits a promise rejection to remain unhandled, so strict Node.js rejection handling terminates the process; the exact request and code locus are undisclosed. Exposure requires Node.js above 15.0.0 with strict rejection exit behavior and next start or a custom server that reuses next-server across requests.
