Pepr is a type safe K8s middleware. Prior to 1.0.5 , Pepr defaults to a cluster-admin RBAC configuration and does not explicitly force or enforce least-privilege guidance for module authors. The default behavior exists to make the “getting started” experience smooth: new users can experiment with Pepr and create resources dynamically without needing to pre-configure RBAC. This vulnerability is fixed in 1.0.5.
