      "value": "Logto is the modern, open-source auth infrastructure for SaaS and AI apps. Prior to 1.41.0, Logto's Account Center step-up check accepted any active verification record that belonged to the current user and had isVerified === true. A WebAuthn registration verification record for binding a new passkey could be created and verified with only an existing Account API bearer token, then sent in the logto-verification-id header and treated as identityVerified=true by Account Center routes, allowing MFA factor management without proving possession of an existing password, identifier, or MFA factor. This issue is fixed in version 1.41.0."

Antes de la versión 1.41.0, la comprobación de elevación de privilegios del Centro de Cuentas de Logto aceptaba cualquier registro de verificación activo que perteneciera al usuario actual y tuviera isVerified === true. Un registro de verificación de registro de WebAuthn para vincular una nueva clave de acceso podía crearse y verificarse con solo un token portador de la API de Cuenta existente, luego enviado en la cabecera logto-verification-id y tratado como identityVerified=true por las rutas del Centro de Cuentas, permitiendo la gestión de factores MFA sin probar la posesión de una contraseña, identificador o factor MFA existente. Este problema está solucionado en la versión 1.41.0."
