Official Description
Clustered Data ONTAP versions prior to 9.3P21, 9.5P16, 9.6P12, 9.7P8 and 9.8 are susceptible to a vulnerability which could allow unauthorized tenant users to discover information related to converting a 7-Mode directory to Cluster-mode such as Storage Virtual Machine (SVM) names, volume names, directory paths and Job IDs.
