CVE-2026-47170Network attack vector

Internal HTTP disclosure via unvalidated upload URL

Published Jun 11, 2026 · Updated Jun 11, 2026

Server-side request forgery in Garlic Signage Garlic-Hub before 1.1 allows remote authenticated users to retrieve internal HTTP responses. The uploadFromUrl path passes an attacker-supplied URL directly to Guzzle HEAD and GET requests without validating the scheme or resolved destination, then saves the GET body in the public media pool. Any authenticated account can scan internal ports and expose reachable HTTP content through the server.
