AI-suggested
Red Hat recommends configuring the application-manager addon in Red Hat Advanced Cluster Management for Kubernetes to use the least-privilege RBAC variant. This involves applying the addon/manifests/permission/role.yaml configuration to restrict the permissions granted to the application-manager ServiceAccount. Administrators should consult Red Hat documentation for detailed instructions on applying custom RBAC configurations for RHACM addons. After applying the configuration, a restart or reload of affected components may be required for changes to take effect.
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.
