A new HIGH severity vulnerability was found in Kubernetes in which users may be able to create a container with subpath volume mounts to access files & directories outside of the volume, including on the host filesystem. The issue is affecting the Kubelet component of Kubernetes (Kubelet is the primary "node agent" that runs on each node. It registers the node with the apiserver and launches PODs on it).

While Kubernetes offers a self-healing deployment platform, there is a fair chance a developer will run into issues that require deeper analysis and debugging to identify configuration problems. Kubernetes supports a loosely coupled, distributed architecture by allowing an application to be broken down into smaller, granular modules—each of which can be written and managed independently.
