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.

What to do
Workaround: To mitigate this issue, Red Hat Advanced Cluster Management for Kubernetes administrators should configure the application-manager addon to use the least-privilege RBAC variant. This involves applying the addon/manifests/permission/role.yaml configuration, which restricts the permissions granted to the application-manager ServiceAccount. Consult Red Hat documentation for specific instructions on how to apply custom RBAC configurations for RHACM addons. Applying this change may require a restart or reload of the affected components to take effect.
