La funci\u00f3n de grupo de pol\u00edticas, agregada por la versi\u00f3n 1.17.0. Al tener un espacio de nombres, AdmissionPolicyGroup tiene un impacto bien restringido en los recursos del cl\u00faster. Por lo tanto, se considera seguro permitir que los usuarios que no son administradores creen y administren estos recursos en los espacios de nombres que poseen. Se puede permitir que las pol\u00edticas de Kubewarden consulten la API de Kubernetes en el momento de la evaluaci\u00f3n; estos tipos de pol\u00edticas se denominan \"conscientes del contexto\". Las pol\u00edticas conscientes del contexto pueden realizar operaciones de lista y obtenci\u00f3n en un cl\u00faster de Kubernetes. Las consultas se realizan utilizando la ServiceAccount de la instancia del servidor de pol\u00edticas que aloja la pol\u00edtica. Eso significa que el acceso al cl\u00faster est\u00e1 determinado por las reglas de RBAC que se aplican a esa ServiceAccount. El CRD de AdmissionPolicyGroup permiti\u00f3 la implementaci\u00f3n de pol\u00edticas conscientes del contexto. Esto podr\u00eda permitir que un atacante obtenga informaci\u00f3n sobre recursos que est\u00e1n fuera de su alcance, aprovechando un mayor acceso al cl\u00faster otorgado al token ServiceAccount utilizado para ejecutar la pol\u00edtica. El impacto de esta vulnerabilidad depende de los privilegios que se hayan otorgado al ServiceAccount utilizado para ejecutar Policy Server y supone que los usuarios est\u00e1n utilizando las mejores pr\u00e1cticas recomendadas para mantener el ServiceAccount del Policy Server con los privilegios m\u00ednimos. De forma predeterminada, el gr\u00e1fico de Helm de Kubewarden otorga acceso \u00fanicamente a los siguientes recursos (en todo el cl\u00faster): espacio de nombres, pod, implementaci\u00f3n e ingreso.
