CVE-2026-52877

Streambert is a cross-platform Electron Desktop App to stream and download video content. Prior to version 2.6.0, the open-external IPC handler in src/ipc/downloads.js passes a renderer-supplied url directly to Electron's shell.openExternal without validating its protocol. A compromised renderer can submit file: URIs or operating-system-specific custom schemes, causing the host to open local files, access remote resources through registered handlers, or launch scripts and applications supported by those handlers. This issue is fixed in version 2.6.0.

Summary		(es) Streambert es una aplicación de escritorio Electron multiplataforma para transmitir y descargar contenido de video. Antes de la versión 2.6.0, el gestor IPC ’open-external’ en src/ipc/downloads.js pasa una URL proporcionada por el renderizador directamente a shell.openExternal de Electron sin validar su protocolo. Un renderizador comprometido puede enviar URIs ’file:’ o esquemas personalizados específicos del sistema operativo, haciendo que el anfitrión abra archivos locales, acceda a recursos remotos a través de gestores registrados o inicie scripts y aplicaciones compatibles con esos gestores. Este problema está solucionado en la versión 2.6.0.
