      "value": "Next.js is a React framework. Starting with version 12.0.0 and prior to version 12.0.9, vulnerable code could allow a bad actor to trigger a denial of service attack for anyone using i18n functionality. In order to be affected by this CVE, one must use next start or a custom server and the built-in i18n support. Deployments on Vercel, along with similar environments where invalid requests are filtered before reaching Next.js, are not affected. A patch has been released, `next@12.0.9`, that mitigates this issue. As a workaround, one may ensure `/${locale}/_next/` is blocked from reaching the Next.js instance until it becomes feasible to upgrade."

Para ser afectado por esta CVE, uno debe usar next start o un servidor personalizado y el soporte i18n incorporado. Los despliegues en Vercel, junto con entornos similares en los que son filtradas las peticiones no v\u00e1lidas antes de llegar a Next.js, no est\u00e1n afectados. Ha sido publicado un parche, \"next@12.0.9\", que mitiga este problema. Como medida de mitigaci\u00f3n, puede asegurarse que \"/${locale}/_next/\" est\u00e9 bloqueado para que no llegue a la instancia de Next.js hasta que sea posible la actualizaci\u00f3n"
