      "value": "Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.1, an authenticated Server-Side Request Forgery (SSRF) vulnerability in the Xibo CMS allows users with Library upload permissions to make arbitrary HTTP requests from the CMS server to internal or external network resources. This can be exploited to scan internal infrastructure, access local cloud metadata endpoints (e.g., AWS IMDS), interact with internal services that lack authentication, or exfiltrate data. This vulnerability is fixed in 4.4.1."

      "value": "Xibo es una plataforma de señalización digital de código abierto con un sistema de gestión de contenido web y software de reproductor de pantalla para Windows. Antes de la versión 4.4.1, una vulnerabilidad autenticada de falsificación de petición del lado del servidor (SSRF) en el CMS de Xibo permite a los usuarios con permisos de carga de biblioteca realizar peticiones HTTP arbitrarias desde el servidor del CMS a recursos de red internos o externos. Esto puede ser explotado para escanear infraestructura interna, acceder a puntos finales de metadatos de la nube locales (por ejemplo, AWS IMDS), interactuar con servicios internos que carecen de autenticación o exfiltrar datos. Esta vulnerabilidad está corregida en la versión 4.4.1."
