Description
Grimoire before 1.0.0 contains an unauthenticated server-side request forgery vulnerability in the /api/fetch-metadata POST handler that passes user-supplied URLs to getMetadata() without authentication checks. Attackers can submit URLs targeting loopback, internal-network, or cloud metadata endpoints and read the parsed title, description, and page content returned.
