Summary

The S3 buckets and keys in a secure Apache Ozone Cluster must be inaccessible to anonymous access by default. The current security vulnerability allows access to keys and buckets through a curl command or an unauthenticated HTTP request. This enables unauthorized access to buckets and keys thereby exposing data to anonymous clients or users. This affected Apache Ozone prior to the 1.1.0 release.
