CVE-2026-70495

Red Hat Red Hat Advanced Cluster Management for Kubernetes 2.11, Red Hat Advanced Cluster Management for Kubernetes 2.13, Red Hat Advanced Cluster Management for Kubernetes 2.14

A flaw was found in search-v2-operator. This component's `search-serviceaccount` has overly broad permissions, allowing it to impersonate users and groups across the entire cluster. If an attacker gains access to any of the pods running under this service account, they could exploit this to achieve `system:masters` access, granting them full control over the cluster.
