AI-suggested

1. Upgrade Yoke to version 0.19.0 or later as soon as a patched release is available to eliminate the vulnerability. 2. Until an upgrade is possible, restrict create and update permissions in Kubernetes to trusted users only, minimizing the risk of malicious annotation injection. 3. Implement strict network policies to limit the ATC controller's ability to download WASM modules from untrusted or external URLs. 4. Monitor Kubernetes audit logs for suspicious use of the overrides.yoke.cd/flight annotation or unusual creation of resources. 5. Employ runtime security tools to detect anomalous behavior in the ATC controller and Kubernetes API server. 6. Conduct regular security reviews of infrastructure-as-code configurations and annotations to detect potential injection points. 7. Educate DevOps and security teams about the risks of code injection in IaC tools and enforce best practices for annotation usage and permissions management.

Description

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. It allows users with CR create/update permissions to execute arbitrary WASM code in the ATC controller context by injecting a malicious URL through the overrides.yoke.cd/flight annotation. The ATC controller downloads and executes the WASM module without proper URL validation, enabling attackers to create arbitrary Kubernetes resources or potentially escalate privileges to cluster-admin level.
