Exploitation requires a namespace \"view\" user to be in a namespace where an InfraEnv references a pull secret that fails assisted-service validation -- a condition the \"view\" user cannot trigger themselves. Red Hat scores UI:R (User Interaction Required) because the leak only exists when an administrator creates or updates an InfraEnv referencing a pull secret that fails validation; without that admin action, there is nothing to exploit. The direct impact is confidentiality: the full pull-secret content is disclosed through InfraEnv status, bypassing the Kubernetes RBAC boundary that prevents \"view\" users from reading Secrets. Red Hat scores I:L (Integrity: Low) rather than I:H because, with Scope: Unchanged, integrity impact should reflect the vulnerable component (MCE/ACM), not external registries. The leaked credential's write capability is conditional on the specific credential's permissions and does not represent integrity compromise of the ACM/MCE cluster itself.\nThe reporter agreed with the new CVSS score.", "threat_severity": "Moderate"}
