      "value": "The Bevy Event service through 2025-07-22, as used for eBay Seller Events and other activities, allows account takeover, if SSO is used, when a victim changes the email address that they have configured. To exploit this, an attacker would create their own account and perform an SSO login. The root cause of the issue is SSO misconfiguration."

      "value": "El servicio Bevy Event hasta el 22-07-2025, tal como se utiliza para los eventos de vendedores de eBay y otras actividades, permite la toma de control de cuentas, si se utiliza SSO, cuando una víctima cambia la dirección de correo electrónico que ha configurado. Para explotar esto, un atacante crearía su propia cuenta y realizaría un inicio de sesión SSO. La causa raíz del problema es una mala configuración de SSO."
