Description
A flaw was found in the multicloud-operators-channel component of Red Hat Advanced Cluster Management (RHACM). This vulnerability allows a compromised agent from a managed cluster to gain unauthorized access to sensitive information. Specifically, the agent can read all Secrets and ConfigMaps within any Channel namespace on the hub, potentially exposing credentials for other tenants' Git and Helm repositories. This could lead to significant information disclosure.
