This is due to improper handling of impersonation group headers, enabling unauthorized administrative access. While the impact of successful exploitation is severe, the attack requires authenticated access to the ACM hub cluster, which is a management-plane component not typically exposed to untrusted networks. Exploitation also depends on knowledge of the cluster-proxy architecture and deliberate construction of requests targeting specific managed clusters. These prerequisites significantly reduce the likelihood of opportunistic or widespread exploitation.", "threat_severity": "Important"}
