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-… 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/n… 💙 We definitely need more security researchers publishing exploit reproductions as code labs anyone can run and verify!

Docker Hands-On: Pass Environment Variables to Containers 🛠️ A container is an isolated and restricted "box" that runs your application. By definition, this means the env vars you set in your terminal won't be visible to the containerized app. Practice: labs.iximiuz.com/challenges/…
