CVE-2026-48616
Full vulnerability record from the local CVENow database.
Description
Rocket.Chat versions <8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7, 7.13.9, 7.10.13 has an access control vulnerability in Livechat files. Protected file downloads at /file-upload/:fileId/:name authorize livechat access using rc_room_type=l with rc_rid+rc_token, but the authorization path does not verify that rc_rid matches the requested file's rid. Furthermore, :fileId is predictable via sequential MongoDB IDs, and :name can be anything, allowing unauthenticated discovery of all uploaded files.

Las descargas de archivos protegidos en /file-upload/:fileId/:name autorizan el acceso a livechat usando rc_room_type=l con rc_rid+rc_token, pero la ruta de autorización no verifica que rc_rid coincida con el rid del archivo solicitado. Además, :fileId es predecible a través de IDs secuenciales de MongoDB, y :name puede ser cualquier cosa, permitiendo el descubrimiento no autenticado de todos los archivos subidos."
