  "details" : [ "Next.js is a React framework for building full-stack web applications. From 13.4.13 to before 15.5.16 and 16.2.5, self-hosted applications using the built-in Node.js server can be vulnerable to server-side request forgery through crafted WebSocket upgrade requests. An attacker can cause the server to proxy requests to arbitrary internal or external destinations, which may expose internal services or cloud metadata endpoints. Vercel-hosted deployments are not affected. This vulnerability is fixed in 15.5.16 and 16.2.5.", "A flaw was found in Next.js. Self-hosted applications utilizing the built-in Node.js server are vulnerable to Server-Side Request Forgery (SSRF) through specially crafted WebSocket upgrade requests. A remote attacker can exploit this by causing the server to proxy requests to arbitrary internal or external destinations. This could lead to the exposure of internal services or sensitive cloud metadata endpoints." ],
