Descriptions

Next.js is an open source website development framework to be used with the React library. In affected versions specially encoded paths could be used when pages/_error.js was statically generated allowing an open redirect to occur to an external site. In general, this redirect does not directly harm users although can allow for phishing attacks by redirecting to an attacker's domain from a trusted domain. We recommend everyone to upgrade regardless of whether you can reproduce the issue or not. The issue has been patched in release 11.1.0.

Next.js es un marco de desarrollo de sitios web de código abierto que se utilizará con la biblioteca React. En las versiones afectadas, rutas especialmente codificadas podrían ser usadas cuando pages/_error.js se generaron estáticamente, lo que permite que se produzca un redireccionamiento abierto a un sitio externo. En general, esta redirección no daña directamente a los usuarios, aunque puede permitir ataques de phishing al redirigir al dominio de un atacante desde un dominio de confianza. Recomendamos a todos que se actualicen, independientemente de si pueden reproducir el problema o no. El problema se corrigió en la versión 11.1.0
