CVE-2026-44424: CWE-639: Authorization Bypass Through User-Controlled Key in shellhub-io shellhub
CVE-2026-44424 is an authorization bypass vulnerability in shellhub versions prior to 0.24.2. The issue occurs because the API endpoint GET /api/devices/:uid returns full device metadata to any authenticated user without verifying device ownership within the caller's namespace. This allows an authenticated user with a valid JWT or API key to access device information from other tenants if they know or can guess the device UID. The vulnerability has a CVSS score of 6.5 (medium severity) and is fixed in version 0.24.2.
AI Analysis
Technical Summary
ShellHub is a centralized SSH gateway. Before version 0.24.2, the GET /api/devices/:uid endpoint does not verify that the requested device belongs to the authenticated user's namespace. As a result, any authenticated user (using JWT or API key) can retrieve full device metadata for devices outside their tenant by knowing or guessing the device UID. This constitutes an authorization bypass vulnerability classified under CWE-639. The issue is resolved in ShellHub version 0.24.2.
Potential Impact
An authenticated user with low privileges can access sensitive device metadata belonging to other tenants. This exposure of device information could lead to privacy violations or aid further targeted attacks. There is no indication of impact on device integrity or availability. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade ShellHub to version 0.24.2 or later, where this authorization bypass vulnerability is fixed. Since the vendor advisory indicates the issue is resolved in 0.24.2, applying this official fix is the recommended remediation. No additional mitigations are specified.
