CVE-2026-23904

Kyuubi Engine UI proxy accepts a host and port from the request path and proxies HTTP requests to that destination. A remote requester with network access to the proxy can cause the Kyuubi server to send HTTP requests to arbitrary reachable hosts, resulting in SSRF or open-proxy behavior. This issue affects Apache Kyuubi: from 1.8.0 before 1.12.0. Users are recommended to upgrade to version 1.12.0, which disables the proxy by default. To restore proxied Engine UI, set kyuubi.frontend.rest.engine.ui.proxy.enabled=true and configure allowed target hosts with kyuubi.frontend.rest.engine.ui.proxy.hosts.

Summary		(es) El proxy de la interfaz de usuario de Kyuubi Engine acepta un host y un puerto de la ruta de la solicitud y actúa como proxy para las solicitudes HTTP a ese destino. Un solicitante remoto con acceso de red al proxy puede hacer que el servidor Kyuubi envíe solicitudes HTTP a hosts arbitrarios accesibles, lo que resulta en SSRF o comportamiento de proxy abierto. Este problema afecta a Apache Kyuubi: desde la versión 1.8.0 hasta antes de la 1.12.0. Se recomienda a los usuarios actualizar a la versión 1.12.0, que deshabilita el proxy por defecto. Para restaurar la interfaz de usuario de Engine con proxy, establezca kyuubi.frontend.rest.engine.ui.proxy.enabled=true y configure los hosts de destino permitidos con kyuubi.frontend.rest.engine.ui.proxy.hosts.
