      Summary Unauthorized host creation via configuration.import API by low-privilege user with write permissions
      Description An authenticated Zabbix user (User role) with template/host write permissions is able to create objects via the configuration.import API. This can lead to confidentiality loss by creating unauthorized hosts. Note that the User role is normally not sufficient to create and edit templates/hosts even with write permissions.
      Known attack vectors Low-privilege user invoking configuration.import to perform unauthorized object creation.
