CVE-2026-63643

MagicMirror² is an open source modular smart mirror platform. Prior to 2.37.0, the ADD_CALENDAR handler in defaultmodules/calendar/node_helper.js accepts an attacker-controlled URL, authentication data, and selfSignedCert setting through the unauthenticated Socket.IO namespace /calendar. The handler passes these fields to CalendarFetcher, causing a server-side request without SSRF validation and optionally disabling TLS verification. When the response is valid iCal, CALENDAR_EVENTS returns parsed event data to the attacker, allowing internal-service response data to be exfiltrated; other responses still provide a blind request and timing primitive. This issue is fixed in version 2.37.0.

Summary		(es) MagicMirror² es una plataforma de espejo inteligente modular de código abierto. Antes de la versión 2.37.0, el gestor ADD_CALENDAR en defaultmodules/calendar/node_helper.js acepta una URL controlada por el atacante, datos de autenticación y la configuración selfSignedCert a través del espacio de nombres Socket.IO no autenticado /calendar. El gestor pasa estos campos a CalendarFetcher, causando una solicitud del lado del servidor sin validación SSRF y deshabilitando opcionalmente la verificación TLS. Cuando la respuesta es un iCal válido, CALENDAR_EVENTS devuelve datos de eventos analizados al atacante, permitiendo la exfiltración de datos de respuesta de servicios internos; otras respuestas aún proporcionan una solicitud ciega y una primitiva de temporización. Este problema se solucionó en la versión 2.37.0.
