How One Kubernetes YAML File Can Compromise Your Entire Google Cloud Organization
A critical security vulnerability in Google Kubernetes Config Connector (KCC) allows attackers with limited Kubernetes namespace access to escalate privileges and gain complete control over entire Google Cloud organizations. The attack, dubbed ConfigConfusion, exploits a confused deputy problem where KCC's organization-level service account executes IAM changes requested by users who lack corresponding Google Cloud permissions. Attackers can submit a single YAML IAMPolicyMember resource to grant themselves roles/owner privileges across the entire organization, effectively bypassing all authentication controls without ever possessing Google Cloud credentials. This vulnerability highlights the growing risks of infrastructure-as-code systems where authorization gaps between Kubernetes RBAC and cloud provider IAM create unprecedented privilege escalation pathways, particularly as organizations increasingly adopt GitOps workflows and multi-cloud architectures.
