An issue was discovered in ManagedClusterView API, that could allow secrets to be disclosed to users without the correct permissions. Views created for an admin user would be made available for a short time to users with only view permission. In this short time window the user with view permission could read cluster secrets that should only be disclosed to admin users.
This issue has been addressed in the following products:
Red Hat Advanced Cluster Management for Kubernetes 2.0 for RHEL 8
Red Hat Advanced Cluster Management for Kubernetes 2.0 for RHEL 7
