 Using wildcards when defining Role-Based Access Control (RBAC) permissions in Kubernetes can lead to significant security issues. This is because it grants overly broad permissions, potentially allowing access to sensitive resources.
 
 
-RBAC is designed to limit the access rights of users within the system by assigning roles to them. These roles define what actions a user can perform and on which resources. When a wildcard is used, it means that the role has access to all resources/verbs, bypassing the principle of least privilege. This principle states that a user should have only the minimal permissions they need to perform their job function.
