A few weeks back Kubernetes had its first really severe security issue, CVE-2018-1002105. For some background on this, and how it was discovered, I recommend Darren Shepherd’s blog post, he discovered it via some side effects and initially it did not appear to be a security issue just an error handling issue. Of course we know well that many error handling issues can be escalated, but why was this one so bad?
