Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when a blank string is used as an HTML attribute name in Action View tag helpers, the attribute escaping is bypassed, producing malformed HTML. A carefully crafted attribute value could then be misinterpreted by the browser as a separate attribute name, possibly leading to XSS. Applications that allow users to specify custom HTML attributes are affected. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch."

Anteriormente a las versiones 8.1.2.1, 8.0.4.1 y 7.2.3.1, cuando se utiliza una cadena vacía como nombre de atributo HTML en los ayudantes de etiquetas de Action View, el escape de atributos se omite, produciendo HTML malformado. Un valor de atributo cuidadosamente elaborado podría entonces ser malinterpretado por el navegador como un nombre de atributo separado, posiblemente llevando a XSS. Las aplicaciones que permiten a los usuarios especificar atributos HTML personalizados se ven afectadas. Las versiones 8.1.2.1, 8.0.4.1 y 7.2.3.1 contienen un parche."
