CVE-2026-44424: CWE-639: Authorization Bypass Through User-Controlled Key in shellhub-io shellhub
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.
AI Analysis
Technical Summary
ShellHub, a centralized SSH gateway, had an authorization bypass vulnerability (CWE-639) in versions before 0.24.2. The API endpoint GET /api/devices/:uid did not verify that the requested device belonged to the authenticated user's namespace, allowing any authenticated user (via JWT or API key) to retrieve full device metadata for devices outside their tenant. This issue was addressed and fixed in version 0.24.2.
Potential Impact
An authenticated user with a valid JWT or API key could access sensitive device metadata belonging to other tenants by guessing or knowing device UIDs. This exposure could lead to unauthorized disclosure of device information. The vulnerability does not impact integrity or availability, only confidentiality of device metadata.
Mitigation Recommendations
Upgrade shellhub to version 0.24.2 or later where this authorization bypass vulnerability is fixed. Since no official patch links or vendor advisory are provided, verify the upgrade from the official shellhub release notes or repository. No other mitigations are specified.
