Prior to 1.36.0, Vaultwarden's SSO login flow checked the IdP email_verified claim only for new-user creation and not when SSO_SIGNUPS_MATCH_EMAIL=true linked an IdP identity to an existing local account, allowing an attacker-controlled IdP identity asserting a victim email address to bind to and authenticate as that account. This issue is fixed in version 1.36.0."

Antes de la versión 1.36.0, el flujo de inicio de sesión SSO de Vaultwarden verificaba la declaración email_verified del IdP solo para la creación de nuevos usuarios y no cuando SSO_SIGNUPS_MATCH_EMAIL=true vinculaba una identidad IdP a una cuenta local existente, permitiendo que una identidad IdP controlada por un atacante que afirmaba una dirección de correo electrónico de la víctima se vinculara y autenticara como esa cuenta. Este problema está solucionado en la versión 1.36.0."
