In order to be affected by this issue, the deployment must use Next.js versions above 11.1.0 and below 12.0.5, Node.js above 15.0.0, and next start or a custom server. Deployments on Vercel are not affected, along with similar environments where invalid requests are filtered before reaching Next.js. Versions 12.0.5 and 11.1.3 contain patches for this issue."

En las versiones de Next.js anteriores a 12.0.5 o 11.1.3, las direcciones URL no v\u00e1lidas o malformadas podr\u00edan conllevar a un bloqueo del servidor. Para verse afectado por este problema, el despliegue debe usar versiones de Next.js superiores a 11.1.0 y anteriores a 12.0.5, Node.js versiones posteriores a 15.0.0, y el siguiente inicio o un servidor personalizado. Los despliegues en Vercel no est\u00e1n afectados, junto con entornos similares en los que las peticiones no v\u00e1lidas son filtradas antes de llegar a Next.js.
