CVE-2026-62283

Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. Nezha versions 1.14.13 through 1.14.14 and 2.0.0 through 2.0.9 do not bind stream identifiers created by CreateStream in service/rpc/io_stream.go to their creating user, and `GET /ws/terminal/:id` and `GET /ws/file/:id` only check whether the supplied UUID exists. An authenticated RoleMember who obtains a live stream UUID from logs, browser history, referer data, or telemetry can attach to another user's terminal or file-manager session, read and write target-server files, and execute shell commands. This issue is fixed in version 2.0.10.

Summary		(es) Nezha Monitoring es una herramienta autoalojable y ligera para el monitoreo de servidores y sitios web, y para O&M. Las versiones de Nezha 1.14.13 a 1.14.14 y 2.0.0 a 2.0.9 no vinculan los identificadores de flujo creados por CreateStream en service/rpc/io_stream.go a su usuario creador, y 'GET /ws/terminal/:id' y 'GET /ws/file/:id' solo verifican si el UUID proporcionado existe. Un RoleMember autenticado que obtiene un UUID de flujo en vivo de registros, historial del navegador, datos de referer o telemetría puede adjuntarse a la sesión de terminal o de gestor de archivos de otro usuario, leer y escribir archivos del servidor de destino, y ejecutar comandos de shell. Este problema se ha solucionado en la versión 2.0.10.
