CVE-2026-47170: CWE-918: Server-Side Request Forgery (SSRF) in garlic-signage garlic-hub
Garlic-Hub manages digital signage network — devices, content, and playlists — from a single self-hosted interface. Prior to version 1.1, authenticated users can cause the server to issue arbitrary HTTP requests to internal services via the uploadFromUrl endpoint. This allows internal port scanning, service fingerprinting, and retrieval of internal HTTP responses which are stored in the publicly accessible media pool. This issue has been patched in version 1.1.
AI Analysis
Technical Summary
CVE-2026-47170 is a CWE-918 SSRF vulnerability affecting garlic-signage garlic-hub before version 1.1. Authenticated users can abuse the uploadFromUrl endpoint to cause the server to issue arbitrary HTTP requests to internal network services. This enables attackers to perform internal port scanning, fingerprint services, and retrieve internal HTTP responses, which are then stored in a publicly accessible media pool, potentially exposing sensitive internal information. The issue is resolved in garlic-hub version 1.1.
Potential Impact
The vulnerability allows authenticated users to perform SSRF attacks, leading to internal network reconnaissance such as port scanning and service fingerprinting. Additionally, internal HTTP responses can be retrieved and exposed publicly, which may disclose sensitive information. There is no indication of direct code execution or denial of service. The CVSS score of 7.7 reflects a high severity with high confidentiality impact but no integrity or availability impact.
Mitigation Recommendations
Upgrade garlic-signage garlic-hub to version 1.1 or later, where this SSRF vulnerability has been patched. Since the vendor advisory confirms the issue is fixed in version 1.1, applying this official fix is the recommended remediation. No other mitigation steps are indicated.
