Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. In versions prior to 0.6.5, due to a miswritten NetworkPolicy, a malicious actor can pivot from an instance to any Pod out of the origin namespace. This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. In the specific case of sdk/kubernetes.Kompose it does not isolate the instances. This issue has been fixed in version 0.6.5.
