CVE-2025-30218

Next.js is a React framework for building full-stack web applications. To mitigate CVE-2025-29927, Next.js validated the x-middleware-subrequest-id which persisted across multiple incoming requests. However, this subrequest ID is sent to all requests, even if the destination is not the same host as the Next.js application. Initiating a fetch request to a third-party within Middleware will send the x-middleware-subrequest-id to that third party. This vulnerability is fixed in 12.3.6, 13.5.10, 14.2.26, and 15.2.4.

Summary		(es) Next.js es un React framework para construir aplicaciones web de pila completa. Para mitigar CVE-2025-29927, Next.js validó el ID X-Middleware-subrequest que persistió en múltiples solicitudes entrantes. Sin embargo, esta ID de subrequest se envía a todas las solicitudes, incluso si el destino no es el mismo host que la aplicación Next.js. Iniciar una solicitud de recuperación a un tercero dentro de Middleware enviará el ID de subrequest de X-Middleware a ese tercero. Esta vulnerabilidad se fija en 12.3.6, 13.5.10, 14.2.26 y 15.2.4.
