Upgrade pepr to version 1.0.5 or higher.
Overview
pepr is a Kubernetes application engine
Affected versions of this package are vulnerable to Incorrect Default Permissions due to the default configuration of rbacMode being set to "admin" in the RBAC setup process. An attacker can gain broader privileges than necessary by deploying a module with cluster-admin role instead of using a more restrictive RBAC mode. This is only exploitable if the user does not review or modify the default RBAC settings during deployment.
