CVE-2026-44015

Nginx UI is a web user interface for the Nginx web server. In 2.3.4 and earlier, an authenticated user can perform Server-Side Request Forgery (SSRF) by creating a cluster node pointing to an arbitrary internal URL and then sending API requests with the X-Node-ID header. The Proxy middleware forwards these requests to the attacker-specified internal address, bypassing network segmentation and enabling access to services bound to localhost or internal networks.

Summary		(es) Nginx UI es una interfaz de usuario web para el servidor web Nginx. En 2.3.4 y versiones anteriores, un usuario autenticado puede realizar falsificación de petición del lado del servidor (SSRF) creando un nodo de clúster que apunte a una URL interna arbitraria y luego enviando peticiones API con la cabecera X-Node-ID. El middleware Proxy reenvía estas peticiones a la dirección interna especificada por el atacante, eludiendo la segmentación de red y permitiendo el acceso a servicios vinculados a localhost o redes internas.
