Graham Helton has just published a disclosure of a Kubernetes vulnerability that allows running arbitrary commands in any pod in a cluster using a common "read-only" RBAC permission. And this vulnerability won't be assigned a CVE, meaning Kubernetes won't receive a fix 🤷‍♂️ grahamhelton.com/blog/nodes-pro… But there is a silver lining. Graham prepared a short auxiliary post that focuses specifically on the reproduction, and it's an iximiuz Labs tutorial: labs.iximiuz.com/tutorials/node… 💙 We definitely need more security researchers publishing exploit reproductions as code labs anyone can run and verify!
