What is Kubernetes RBAC impersonation and what security implications does it have?

Accepted Answer

Kubernetes RBAC impersonation enables authenticated users or service accounts to assume another identity. This is useful for debugging and testing, but poses security risks if over-granted. The correct answer highlights this dual nature. Incorrect options misrepresent impersonation as pod-to-pod interaction or an attack vector.
