Plain English Summary

AI-powered analysis for quick understanding

An attacker can execute malicious code on the Yoke system, potentially gaining control over Kubernetes resources or escalating their privileges to the highest level. This vulnerability requires the attacker to have permissions to create or update resources in the system.

Technical 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.
