value : An improper HTML sanitization in Dart versions up to and including 2.7.1 and dev versions 2.8.0-dev.16.0, allows an attacker leveraging DOM Clobbering techniques to skip the sanitization and inject custom html/javascript (XSS). Mitigation: update your Dart SDK to 2.7.2, and 2.8.0-dev.17.0 for the dev version. If you cannot update, we recommend you review the way you use the affected APIs, and pay special attention to cases where user-provided data is used to populate DOM nodes. Consider using Element.innerText or Node.text to populate DOM elements. (string)

value : Un saneamiento HTML inapropiado en Dart versiones hasta 2.7.1 y las versiones dev 2.8.0-dev.16.0, permite a un atacante aprovechar las técnicas DOM Clobbering para omitir el saneamiento e inyectar html/javascript personalizado (XSS). Mitigación: actualizar su Dart SDK a versión 2.7.2 y a versión 2.8.0-dev.17.0 para la versión de desarrollo. Si no puede actualizar, le recomendamos que revise la manera en que usa las API afectadas y preste especial atención a los casos en los que los datos provistos por el usuario son utilizados para completar los nodos DOM. Considere usar Element.innerText o Node.text para llenar los elementos DOM. (string)
