Description

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&#39;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.
