An outline of such a policy is provided below:\n\n```\napiVersion: \"cilium.io/v2\"\nkind: CiliumClusterwideNetworkPolicy\nmetadata:\n name: \"workaround\"\nspec:\n endpointSelector:\n matchExpressions:\n - key: reserved:ingress\n operator: Exists\n ingress:\n - fromEntities:\n - world\n```\n\n- The policy opens up connectivity from all locations outside the cluster into the Cilium Ingress Gateway.\n- The policy establishes a default deny for all other traffic towards the Cilium Ingress Gateway, including all in-cluster sources.\n- It is possible to tailor the policy to more narrowly allow inbound traffic while creating a default deny posture for traffic between namespaces. Users should edit the policy to bring it in line with the security requirements particular to their environments.\n\n### Acknowledgements\n\nThe Cilium community has worked together with members of the Isovalent team to prepare these mitigations. Special thanks to @jrajahalme for the fix.\n\n### For more information\n\nIf you think you have found a vulnerability affecting Cilium, we strongly encourage you to report it to our security mailing list at [security@cilium.io](mailto:security@cilium.io).
