CVE-2026-42220

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, an authenticated user can call GET /api/settings and retrieve sensitive configuration values, including node.secret. The same node.secret is accepted by AuthRequired() through the X-Node-Secret header (or node_secret query parameter), causing the request to be treated as authenticated via the trusted-node path and associated with the init user. This issue has been patched in version 2.3.8.

Summary		(es) Nginx UI es una interfaz de usuario web para el servidor web Nginx. Antes de la versión 2.3.8, un usuario autenticado puede llamar a GET /api/settings y recuperar valores de configuración sensibles, incluyendo node.secret. El mismo node.secret es aceptado por AuthRequired() a través del encabezado X-Node-Secret (o el parámetro de consulta node_secret), haciendo que la solicitud sea tratada como autenticada a través de la ruta trusted-node y asociada con el usuario init. Este problema ha sido parcheado en la versión 2.3.8.
