      "value": "MWDB Core versions >=2.2.0 and <2.19.0 contain a missing authorization vulnerability in the Remote Instances proxy API. The proxy API does not verify authentication for incoming requests, allowing an unauthenticated remote attacker to send arbitrary requests to a remote MWDB instance using the identity and permissions associated with the configured API key. This can result in unauthorized actions being performed on the remote instance as if executed by the user whose API key was used to set up the remote instance. The vulnerability is limited to deployments where Remote Instances have been configured.This issue has been fixed in version 2.19.0"

      "value": "Las versiones de MWDB Core >=2.2.0 y anterior a 2.19.0 contienen una vulnerabilidad de autorización faltante en la API proxy de Instancias Remotas. La API proxy no verifica la autenticación para las solicitudes entrantes, permitiendo a un atacante remoto no autenticado enviar solicitudes arbitrarias a una instancia remota de MWDB utilizando la identidad y los permisos asociados con la clave API configurada. Esto puede resultar en que se realicen acciones no autorizadas en la instancia remota como si fueran ejecutadas por el usuario cuya clave API se utilizó para configurar la instancia remota. La vulnerabilidad está limitada a las implementaciones donde se han configurado Instancias Remotas. Este problema ha sido solucionado en la versión 2.19.0."
