Vulnerability from fkie_nvd - Published: 2026-05-13 22:16 - Updated: 2026-05-18 13:35
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/devices/:uid returns the full device object whenever the caller is authenticated, without verifying that the device belongs to the caller's namespace (tenant). Any authenticated user (JWT or API Key) who knows or can guess a device UID can read device metadata from any other namespace. This vulnerability is fixed in 0.24.2.
