Researcher says Google Cloud Config Connector flaw can bypass IAM and give attackers control of GCP organizations

A researcher says an unpatched flaw in Google Cloud's Config Connector could let a Kubernetes user seize broad control of an organization's Google Cloud environment. The issue, dubbed ConfigConfusion, affects Config Connector, Google's open source Kubernetes add-on for managing cloud resources, and allegedly lets a namespace user abuse a missing authorization check to bypass Identity and Access Management (IAM) and assign owner-level permissions at the Google Cloud Organization level. No CVE or patch has been issued.
Why it matters: Organizations using Config Connector with high-privilege service accounts could be exposed to full cloud-environment takeover if the report is accurate. Defenders using Google Cloud and Kubernetes should urgently review Config Connector deployments, reduce org-level permissions, and watch for vendor guidance or a fix.
