Descriptions

In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, arbitrary local file read is possible by defining unsafe window options on a child window opened via window.open. As a workaround, ensure you are calling `event.preventDefault()` on all new-window events where the `url` or `options` is not something you expect. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4.

En Electron antes de las versiones 7.2.4, 8.2.4 y 9.0.0-beta21, una lectura arbitraria de archivos locales es posible al definir opciones de ventana no seguras en una ventana secundaria abierta por medio de window.open. Como solución alternativa, asegúrense de llamar a la función "event.preventDefault()" en todos los eventos de ventanas nuevas donde la "url" u "options" no es algo que se espera. Esto es corregido en las versiones 9.0.0-beta.21, 8.2.4 y 7.2.4
