Prior to 0.5.6, 9Router deployments that allow requests to reach Next.js without the sanitizing custom-server.js wrapper trust the client-supplied X-9r-Real-Ip header in src\/dashboardGuard.js when isLocalRequest decides whether canAccessPublicLlmApi may skip API-key validation for \/api\/v1\/* routes. A remote unauthenticated attacker can set X-9r-Real-Ip to 127.0.0.1 and be classified as a local client, including on the verified GET \/api\/v1\/models route.
