Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer. In 0.19.0 and earlier, a vulnerability exists in the Air Traffic Controller (ATC) component of Yoke. The ATC webhook endpoints lack proper authentication mechanisms, allowing any pod within the cluster network to directly send AdmissionReview requests to the webhook, bypassing Kubernetes API Server authentication. This enables attackers to trigger WASM module execution in the ATC controller context without proper authorization.
AnalysisAI
Unauthenticated webhook endpoints in Yoke's Air Traffic Controller component allow any pod within a Kubernetes cluster to submit AdmissionReview requests and execute WASM modules in the controller's context without authorization. This affects Yoke versions 0.19.0 and earlier, enabling attackers with cluster access to bypass API Server authentication and potentially compromise the infrastructure-as-code deployment pipeline. No patch is currently available.
