No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
