By being namespaced, the AdmissionPolicyGroup has a well constrained impact on cluster resources. Hence, it’s considered safe to allow non-admin users to create and manage these resources in the namespaces they own. Kubewarden policies can be allowed to query the Kubernetes API at evaluation time; these types of policies are called “context aware“. Context aware policies can perform list and get operations against a Kubernetes cluster. The queries are done using the ServiceAccount of the Policy Server instance that hosts the policy. That means that access to the cluster is determined by the RBAC rules that apply to that ServiceAccount. The AdmissionPolicyGroup CRD allowed the deployment of context aware policies. This could allow an attacker to obtain information about resources that are out of their reac
