Detailsinfo

A vulnerability, which was classified as problematic, has been found in shellhub-io shellhub up to 0.24.1. This issue affects an unknown code of the file /api/namespaces/:tenant. The manipulation with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. Impacted is confidentiality. The summary by CVE is:

ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/namespaces/:tenant returns the full namespace object — including the members list (user IDs, e-mails, roles), settings, and device counts — to any caller authenticated by an API Key, for any tenant, regardless of the API Key's own tenant scope. The handler conditionally skips the membership check when the user ID (X-ID) is absent, which is exactly the case for API Key authentication. This vulnerability is fixed in 0.24.2.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-44426 since 05/06/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available.
