CVE-2026-72508 A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM)
Description
A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM). This vulnerability allows a namespace-admin tenant to perform a confused-deputy attack by creating Subscription Custom Resources (CRs) that leverage a highly privileged ServiceAccount (SA). This enables the tenant to deploy arbitrary cluster-scoped resources, leading to privilege escalation and potential arbitrary code execution across the cluster.
