      "value": "A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only."

      "value": "Un componente del controlador de MongoDB podría escribir información de configuración sensible, incluyendo una credencial utilizada para la conectividad de red saliente, en la salida de los registros de la aplicación en texto claro durante la inicialización rutinaria del cliente. Esto ocurre automáticamente como parte de la operación normal y no requiere privilegios especiales para activarse. Una parte capaz de leer los registros de la aplicación afectada o el almacenamiento de agregación de registros posterior podría recuperar la credencial y reutilizarla para autenticarse en la infraestructura de red asociada. Este problema afecta solo a la confidencialidad."
