      "value": "In Splunk AI Toolkit versions below 5.7.4, a user who holds the \"admin\" Splunk role could execute arbitrary OS commands on the host running the Splunk Enterprise instance.  \n\nThe vulnerability is possible because of an unsafe shell execution pattern in the btool configuration helper, which constructs OS command strings from dynamic parameters without disabling shell interpretation."

      "value": "En versiones de Splunk AI Toolkit anteriores a la 5.7.4, un usuario con el rol de Splunk ’admin’ podría ejecutar comandos arbitrarios del sistema operativo en el host que ejecuta la instancia de Splunk Enterprise.\n\nLa vulnerabilidad es posible debido a un patrón de ejecución de shell inseguro en el asistente de configuración btool, que construye cadenas de comandos del sistema operativo a partir de parámetros dinámicos sin deshabilitar la interpretación de shell."
