The exploitation of a high-severity Kubernetes vulnerability can lead to arbitrary code execution with System privileges on all Windows endpoints in a cluster, Akamai warns.

The issue, tracked as CVE-2023-5528 and impacting default Kubernetes installations, exists in the way the open source container orchestration system processes YAML files, which it uses for virtually every function.

In some regards, the vulnerability is like CVE-2023-3676, a lack of sanitization in the subPath parameter in YAML files leading to code injection when creating pods with volumes.
