CVE-2026-72802

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the resolveAssetPath endpoint that returns absolute filesystem paths unmodified to CheckAuth-only requests. Attackers can harvest relative asset paths from published documents and submit them to resolveAssetPath to obtain the server's absolute workspace path, disclosing the operating-system username and installation layout.

Summary		(es) Las versiones de SiYuan anteriores a la v3.7.4 contienen una vulnerabilidad de revelación de información en el endpoint resolveAssetPath que devuelve rutas absolutas del sistema de archivos sin modificar a solicitudes de solo CheckAuth. Los atacantes pueden recolectar rutas de activos relativas de documentos publicados y enviarlas a resolveAssetPath para obtener la ruta absoluta del espacio de trabajo del servidor, revelando el nombre de usuario del sistema operativo y el diseño de la instalación.
