CVE-2026-48616
CVSS v3.1
9.3
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N |
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.
