  "summary" : "Chall-Manager's invalid NetworkPolicy enables a malicious actor to pivot into another namespace",
  "details" : "### Impact\n\nDue to a mis-written NetworkPolicy, a malicious actor can pivot from an instance to any Pod out of the origin namespace.\nThis breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement.\nIn the specific case of `sdk/kubernetes.Kompose` it does not isolate the instances.\n\n### Patch\n\nRemoving the `inter-ns` NetworkPolicy patches the vulnerability. If updates are not possible in production environments, we recommend to manually delete it and update as soon as possible.\n\n### Workaround\n\nGiven your context, delete the failing network policy that should be prefixed by `inter-ns-` in the target namespace.\nYou can use the following to delete all matching network policy. If unsure of the outcome, please do it manually.\n\n```bash\nfor ns in $(kubectl get ns -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\\n' | grep '^cm-target-'); do\n  kubectl -n \"$ns\" get networkpolicy -o name \\\n  | grep '^networkpolicy.networking.k8s.io/inter-ns-' \\\n  | xargs -r kubectl -n \"$ns\" delete\ndone\n```",
