ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/sessions/:uid returns the full session object for any authenticated caller, without scoping by the caller's tenant. An authenticated user can read session records (SSH username, device UID, remote IP, terminal type, authenticated flag, timestamps) belonging to any other namespace. This vulnerability is fixed in 0.24.2.
