Debido a que la cadena resultante es pegada directamente en el nodo de texto del elemento, esto no resulta en una inyecci\u00f3n directa en la p\u00e1gina web; sin embargo, si una p\u00e1gina web posteriormente copia el innerHTML del nodo y lo asigna a otro innerHTML, esto generar\u00eda una vulnerabilidad XSS. Dos editores WYSIWYG fueron identificados con este comportamiento, pueden existir m\u00e1s.
