Descriptions

Next.js versions >=9.5.0 and <9.5.4 are vulnerable to an Open Redirect. Specially encoded paths could be used with the trailing slash redirect to allow 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 attackers domain from a trusted domain. The issue is fixed in version 9.5.4.

Next.js versiones de posteriores e incluyendo a 9.5.0 y anteriores a 9.5.4, son vulnerables a un redireccionamiento abierto. Pueden ser utilizadas rutas especialmente codificadas con el redireccionamiento de la barra diagonal para permitir que se produzca una redireccionamiento abierto hacia un sitio externo. En general, este redireccionamiento abierto no daña directamente a usuarios, aunque puede permitir ataques de phishing al redirigir a un dominio de atacantes desde un dominio de confianza. El problema es corregido en la versión 9.5.4
