      "value": "Next.js is a React framework for building full-stack web applications. Prior to versions 14.2.32 and 15.4.7, when next() was used without explicitly passing the request object, it could lead to SSRF in self-hosted applications that incorrectly forwarded user-supplied headers. This vulnerability has been fixed in Next.js versions 14.2.32 and 15.4.7. All users implementing custom middleware logic in self-hosted environments are strongly encouraged to upgrade and verify correct usage of the next() function."

Antes de las versiones 14.2.32 y 15.4.7, cuando se utilizaba next() sin pasar explícitamente el objeto de solicitud, podría conducir a SSRF en aplicaciones autoalojadas que reenviaban incorrectamente los encabezados proporcionados por el usuario. Esta vulnerabilidad ha sido corregida en las versiones 14.2.32 y 15.4.7 de Next.js. Se recomienda encarecidamente a todos los usuarios que implementan lógica de middleware personalizada en entornos autoalojados actualizar y verificar el uso correcto de la función next()."
