  "details": "### Impact\n\nDue to a mis-written NetworkPolicy, a malicious actor can pivot from a subverted application 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.\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 $(kubectl get ns -o jsonpath=\u0027{.items[*].metadata.name}\u0027 | tr \u0027 \u0027 \u0027\\n\u0027 | grep \u0027^ns-\u0027); do\n  kubectl -n \"$ns\" get networkpolicy -o name \\\n  | grep \u0027^networkpolicy.networking.k8s.io/inter-ns-\u0027 \\\n  | xargs -r kubectl -n \"$ns\" delete\ndone\n```",
