"summary": "Kubewarden: Cross-namespace data exfiltration via deprecated host callback binding",
10+
"details": "### Impact\n\nKubewarden is a policy engine for Kubernetes. Kubewarden cluster operators can grant permissions to users to deploy namespaced AdmissionPolicies and AdmissionPolicyGroups in their Namespaces. One of Kubewarden promises is that configured users can deploy namespaced policies in a safe manner, without privilege escalation.\n\nAn attacker with privileged \"AdmissionPolicy\" create permissions (which isn't the default) could make use of 3 deprecated host-callback APIs: `kubernetes/ingresses`, `kubernetes/namespaces`, `kubernetes/services`.\nThe attacker can craft a policy that exercises these deprecated API calls and would allow them read access to Ingresses, Namespaces, and Services resources respectively.\n\nThis attack is read-only, there is no write capability and no access to Secrets, ConfigMaps, or other resource types beyond these three. The attacker could read for example:\n- Namespace names and labels.\n- Services across all namespaces with ClusterIPs and ports to reveal cluster internal topology.\n- Ingresses across all namespaces with hostnames and routing rules.\n\n### Patches\nThe vulnerable, already deprecated host-capabilities (`kubernetes/ingresses`, `kubernetes/namespaces`, `kubernetes/services`)\nhave been removed.\n\nThe removed calls were not being exercised by any Kubewarden SDK.\n\nThese host-callbacks had already been superseded for a long time by `kubewarden/kubernetes/list_resources_by_namespace`, `kubewarden/kubernetes/list_resources`, and `kubewarden/kubernetes/get_resource`. They provide similar capabilities while being more fine-grained, performant, and gated through our context-aware permissions feature. These current host-capabilities are part of the Kubernetes capabilities listed in our [docs](https://docs.kubewarden.io/reference/spec/host-capabilities/kubernetes).\n\n### Workarounds\nKubewarden operators can update the policy-server image used by their PolicyServers to tag `:v1.33.0`.\nAlternatively, Kubewarden operators can temporarily reduce the permissions of users to prevent them from creating or updating existing namespaced AdmissionPolicies or AdmissionPolicyGroups.",
