Estado: ModificadaMedia (6.1)—

Blink en Google Chrome anterior a 55.0.2883.75 para Linux y Windows y 55.0.2883.84 para Android permitió una posible corrupción del árbol DOM durante el manejo del evento sincronizado, lo que permitió a un atacante remoto inyectar secuencias de comandos o HTML arbitrarios (UXSS) a través de una página HTML manipulada.
