Descriptions

Brave Browser before 0.13.0 allows remote attackers to cause a denial of service (resource consumption) via a long alert() argument in JavaScript code, because window dialogs are mishandled.

Brave Browser, en versiones anteriores a la 0.13.0, permite que atacantes remotos provoquen una denegación de servicio (consumo de recursos) mediante un argumento alert() largo en código JavaScript, ya que se gestionan de manera incorrecta los diálogos de ventana.

Brave Browser versions prior to 0.13.0 suffer from a long alert() argument denial of service vulnerability.
