CVE-2026-56677: CWE-306: Missing Authentication for Critical Function in decolua 9routerCVE-2026-56677 0 CVE-2026-56677 is a high-severity vulnerability in decolua 9router version 0.5.4 and earlier. It involves a missing authentication check on the POST /api/auth/oidc/test endpoint, which allows unauthenticated attackers to supply a user-controlled issuerUrl parameter. This parameter is passed to a function that fetches OIDC discovery data without restricting access to private or loopback network destinations. As a result, attackers can scan internal services and obtain sensitive OpenID Connect discovery information such as token_endpoint and jwks_uri, even when dashboard login is disabled.
