Description
A flaw was found in the multicloud-operators-subscription component. This vulnerability allows a tenant, who has the ability to create HelmRelease custom resources (CRs), to bypass existing security controls. The system's HelmRelease controller processes Helm chart templates using its own elevated ServiceAccount privileges without proper validation. This enables the tenant to deploy arbitrary resources across the entire cluster, leading to a significant security compromise.
