Description
New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Starting in version 0.10.0, a logic flaw in the universal secure verification flow allows an authenticated user with a registered passkey to satisfy secure verification without completing a WebAuthn assertion. As of time of publication, no known patched versions are available. Until a patched release is applied, do not rely on passkey as the step-up method for privileged secure-verification actions; require TOTP/2FA for those actions where operationally possible; or temporarily restrict access to affected secure-verification-protected endpoints.
