Descripción técnica

9Router is an AI router & token saver. In 0.5.4 and earlier, the POST /api/auth/oidc/test endpoint in src/app/api/auth/oidc/test/route.js passes the user-controlled issuerUrl parameter to fetchOidcDiscovery() in src/lib/auth/oidc.js without restricting private or loopback destinations, allowing unauthenticated attackers when dashboard login is disabled to scan internal services and reflect OIDC discovery fields including token_endpoint and jwks_uri.
