CVE-2026-33011

  3. CVE-2026-33011
Nest is a framework for building scalable Node.js server-side applications. In versions 11.1.15 and below, a NestJS application using @nestjs/platform-fastify GET middleware can be bypassed because Fastify automatically redirects HEAD requests to the corresponding GET handlers (if they exist). As a result: middleware will be completely skipped, the HTTP response won't include a body (since the response is truncated when redirecting a HEAD request to a GET handler), and the actual handler will still be executed. This issue is fixed in version 11.1.16.

Summary
  • (es) Nest es un framework para construir aplicaciones escalables de servidor Node.js. En las versiones 11.1.15 e inferiores, una aplicación NestJS que utiliza el middleware GET de @nestjs/platform-fastify puede ser eludida porque Fastify redirige automáticamente las solicitudes HEAD a los gestores GET correspondientes (si existen). Como resultado: el middleware será completamente omitido, la respuesta HTTP no incluirá un cuerpo (ya que la respuesta se trunca al redirigir una solicitud HEAD a un gestor GET), y el gestor real seguirá ejecutándose. Este problema está solucionado en la versión 11.1.16.
