During a ManagedClusterMigration, the system incorrectly grants all managed hubs read access to a shared communication topic. This allows a compromised managed hub to intercept and collect sensitive bootstrap kubeconfigs, which contain API server tokens intended for other hubs. These tokens have an extended validity of approximately 9.86 years, significantly increasing the risk of unauthorized access and information disclosure to other managed clusters.</p> <p><strong>Affected:</strong> Red Hat Multicluster Global Hub 1.4.9, Red Hat Multicluster Global Hub 1.5.8, Red Hat Multicluster Global Hub 1.6.6, Red Hat Multicluster Global Hub 1.7.3, Red Hat Multicluster Global Hub 1.8.2</p> <p>A flaw was found in multicluster-global-hub.
