This permission is used by the Kubernetes Engine Service Agent role (among others) to impersonate a Workload Identity. Thus, it is meant to be used by machine identities, workloads running on the Kubernetes cluster that need to access other Google Cloud services. Access to this permission leads to lateral movement by allowing human principals to act as Kubernetes workloads.

Risks

1. Lateral movement (BOOST)

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
