CVE-2025-6017· NVD / CVE Program· CNA redhat

Rhacm: users with clusterreader role can see credentials from managed-clusters

A flaw was found in Red Hat Advanced Cluster Management through versions 2.10, before 2.10.7, 2.11, before 2.11.4, and 2.12, before 2.12.4. This vulnerability allows an unprivileged user to view confidential managed cluster credentials through the UI. This information should only be accessible to authorized users and may result in the loss of confidentiality of administrative information, which could be leaked to unauthorized actors.
