      "value": "Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.4, a Server-Side Request Forgery (SSRF) vulnerability exists in the Glances IP plugin due to improper validation of the public_api configuration parameter. The value of public_api is used directly in outbound HTTP requests without any scheme restriction or hostname/IP validation. An attacker who can modify the Glances configuration can force the application to send requests to arbitrary internal or external endpoints. Additionally, when public_username and public_password are set, Glances automatically includes these credentials in the Authorization: Basic header, resulting in credential leakage to attacker-controlled servers. This vulnerability can be exploited to access internal network services, retrieve sensitive data from cloud metadata endpoints, and/or exfiltrate credentials via outbound HTTP requests. The issue arises because public_api is passed directly to the HTTP client (urlopen_auth) without validation, allowing unrestricted outbound connections and unintended disclosure of sensitive information. Version 4.5.4 contains a patch."

      "value": "Glances es una herramienta de monitorización de sistemas multiplataforma de código abierto. Antes de la versión 4.5.4, existe una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en el plugin IP de Glances debido a una validación incorrecta del parámetro de configuración public_api. El valor de public_api se utiliza directamente en peticiones HTTP salientes sin ninguna restricción de esquema o validación de nombre de host/IP. Un atacante que puede modificar la configuración de Glances puede forzar a la aplicación a enviar peticiones a puntos finales internos o externos arbitrarios. Además, cuando public_username y public_password están configurados, Glances incluye automáticamente estas credenciales en la cabecera ’Authorization: Basic’, lo que resulta en una fuga de credenciales a servidores controlados por el atacante. Esta vulnerabilidad puede ser explotada para acceder a servicios de red internos, recuperar datos sensibles de puntos finales de metadatos en la nube y/o exfiltrar credenciales a través de peticiones HTTP salientes. El problema surge porque public_api se pasa directamente al cliente HTTP (urlopen_auth) sin validación, permitiendo conexiones salientes sin restricciones y la divulgación no intencionada de información sensible. La versión 4.5.4 contiene un parche."
