# GCP IAM Privilege Escalation

## Purpose
Prove GCP escalation from a starting principal to a higher-privilege identity or effective permission — typically service account impersonation (actAs / token mint / signBlob) or policy modification — with the previously unavailable action demonstrated. A broad role detected is never equivalent to successful escalation.

## Entry Conditions
- Validated GCP credential with an effective-permission map (`gcp-cloud-pentesting` steps 1–2)
- Runtime authorization for state-changing operations

## Attack Model

```text
starting identity
→ escalation primitive (actAs / token mint / policy set / deploy with SA)
