Description OSIDB Bzimport 2026-08-11 17:38:23 UTC 
A flaw was found in the multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM). The application-manager addon's ClusterRole grants apiGroups:* resources:* verbs:* (plus nonResourceURLs:*) and is bound to the application-manager ServiceAccount on every managed cluster via the addon framework. This wildcard RBAC is the root enabler for multiple confused-deputy attacks where a namespace-admin tenant can create Subscription CRs that deploy arbitrary cluster-scoped resources using this privileged SA. A least-privilege variant exists in addon/manifests/permission/role.yaml but is not used by default.
