Official description

Microsoft has identified a vulnerability affecting the cluster connect feature of Azure Arc-enabled Kubernetes clusters. This vulnerability could allow an unauthenticated user to elevate their privileges and potentially gain administrative control over the Kubernetes cluster. Additionally, because Azure Stack Edge allows customers to deploy Kubernetes workloads on their devices via Azure Arc, Azure Stack Edge devices are also vulnerable to this vulnerability.
