Is this vulnerability remotely exploitable across the internet?

Typically, no. Exploitation depends on access to the Kubernetes API with permissions to create or update the relevant custom resources. However, in many organizations, internal users or workloads may have these permissions, which still presents a high-risk scenario.

What level of access does an attacker need to exploit this issue?

An attacker needs authenticated access to the cluster and the ability to create or modify the Yoke-related custom resources processed by the ATC controller, including setting the `overrides.yoke.cd/flight` annotation. They do not need direct access to the controller's host or pods.

What is the safest general fix pattern for this class of bug?

The safest pattern is to decouple configuration from arbitrary code execution by: - Eliminating user-provided URLs as direct inputs to module loaders. - Restricting module execution to a curated set of trusted, signed artifacts. - Narrowing the controller's RBAC permissions so even if a module is abused, its blast radius is minimized.
