Description
A flaw was found in the `submariner-operator` component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability allows a cluster administrator, or any user with permissions to modify the Submariner Custom Resource (CR), to specify an unvalidated image path. This lack of validation enables an attacker to execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes, by deploying a malicious image.
