kubewarden-controller cross-namespace data exfiltration via deprecated host callback binding

Kubewarden 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. An 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. The attacker can craft a policy that exercises these deprecated API calls and would allow them read access to Ingresses, Namespaces, and Services resources respectively. This attack is read-only, there is no write capability and no access to Secrets, ConfigMaps, or other resource types beyond these three.

SUSE kubewarden 安全漏洞

SUSE kubewarden是德国SUSE公司的一个策略引擎。 Kubewarden存在安全漏洞，该漏洞源于具有特定权限的攻击者可利用已弃用的主机回调API部署策略，可能导致读取Ingresses、Namespaces和Services资源。
