      "value": "In Splunk AI Toolkit versions below 5.7.4, a low-privileged user that does not hold the \"admin\" or \"power\" Splunk roles could cause the Splunk AI Toolkit to make outbound requests over HTTP to a server that an attacker controls, which could allow for data exfiltration.  \n\nThe vulnerability exists because of an insecure default domain allowlist in the Splunk AI Toolkit, which does not restrict outbound AI agent  requests to approved external domains."

      "value": "En versiones de Splunk AI Toolkit anteriores a la 5.7.4, un usuario con privilegios bajos que no posee los roles de Splunk ’admin’ o ’power’ podría hacer que Splunk AI Toolkit realizara solicitudes salientes a través de HTTP a un servidor que un atacante controla, lo que podría permitir la exfiltración de datos.\n\nLa vulnerabilidad existe debido a una lista de dominios permitidos (allowlist) predeterminada e insegura en Splunk AI Toolkit, que no restringe las solicitudes salientes del agente de IA a dominios externos aprobados."
