CVE-2026-25552

Ghost CLI before 1.30.1 contains an IP spoofing vulnerability that allows unauthenticated remote attackers to bypass rate-limiting controls by manipulating the X-Forwarded-For header through a misconfigured Nginx configuration. Attackers can append attacker-controlled values to the header chain using the $proxy_add_x_forwarded_for directive to present an arbitrary IP address, circumventing Ghost's rate-limiting mechanisms on self-hosted instances.

Summary		(es) Ghost CLI anterior a 1.30.1 contiene una vulnerabilidad de suplantación de IP que permite a atacantes remotos no autenticados eludir los controles de limitación de velocidad manipulando el encabezado X-Forwarded-For a través de una configuración de Nginx mal configurada. Los atacantes pueden añadir valores controlados por el atacante a la cadena del encabezado utilizando la directiva $proxy_add_x_forwarded_for para presentar una dirección IP arbitraria, eludiendo los mecanismos de limitación de velocidad de Ghost en instancias autoalojadas.
