      "value": "Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, Chamilo LMS contains a Server-Side Request Forgery (SSRF) vulnerability in the Social Wall feature. The endpoint read_url_with_open_graph accepts a URL from the user via the social_wall_new_msg_main POST parameter and performs two server-side HTTP requests to that URL without validating whether the target is an internal or external resource. This allows an authenticated attacker to force the server to make arbitrary HTTP requests to internal services, scan internal ports, and access cloud instance metadata. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3."

      "value": "Chamilo LMS es un sistema de gestión del aprendizaje. Antes de 1.11.38 y 2.0.0-RC.3, Chamilo LMS contiene una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en la característica Muro Social. El endpoint read_url_with_open_graph acepta una URL del usuario a través del parámetro POST social_wall_new_msg_main y realiza dos peticiones HTTP del lado del servidor a esa URL sin validar si el objetivo es un recurso interno o externo. Esto permite a un atacante autenticado forzar al servidor a realizar peticiones HTTP arbitrarias a servicios internos, escanear puertos internos y acceder a metadatos de instancias en la nube. Esta vulnerabilidad está corregida en 1.11.38 y 2.0.0-RC.3."
