Hitachi Vantara Pentaho Data Integration & Analytics versions before 10.2.0.6 and 11.0.0.0, including 9.3.x and 8.3.x, expose Hadoop cluster credentials in plain text through the Cluster Test API. Although the user should not see those explicitly, the defect is mitigated by the fact the user can already leverage those credentials to submit jobs under the same account through the backend API.
