Versions prior to 14.2.24 and 15.1.6 have a race-condition vulnerability. This issue only affects the Pages Router under certain misconfigurations, causing normal endpoints to serve `pageProps` data instead of standard HTML. This issue was patched in versions 15.1.6 and 14.2.24 by stripping the `x-now-route-matches` header from incoming requests. Applications hosted on Vercel's platform are not affected by this issue, as the platform does not cache responses based solely on `200 OK` status without explicit `cache-control` headers. Those who self-host Next.js deployments and are unable to upgrade immediately can mitigate this vulnerability by stripping the `x-now-route-matches` header from all incoming requests at the content development network and setting `cache-control: no-store` for all responses under risk. The maintainers of Next.js strongly recommend only caching responses with explicit cache-control headers."}, {"lang": "es", "value": "Next.js es un framework de React para crear aplicaciones web full-stack.

Las aplicaciones alojadas en la plataforma Vercel no se ven afectadas, ya que la plataforma no almacena en cach\u00e9 las respuestas bas\u00e1ndose \u00fanicamente en el estado `200 OK` sin encabezados `cache-control` expl\u00edcitos. Quienes alojan implementaciones de Next.js en sus propias instalaciones y no pueden actualizar inmediatamente pueden mitigar esta vulnerabilidad eliminando el encabezado `x-now-route-matches` de todas las solicitudes entrantes en la red de desarrollo de contenido y configurando `cache-control: no-store` para todas las respuestas en riesgo.
