The vulnerability occurs in configurations where foreign content is allowed, i.e. either `svg` or `math` are in the list of allowed elements. In the case an application sanitizes user input with a vulnerable configuration, an attacker could bypass the sanitization and inject arbitrary HTML, including JavaScript code. Note that in the default configuration the vulnerability is not present. The vulnerability has been fixed in versions 8.0.723 and 8.1.722-beta (preview version)."},{"lang":"es","value":"HtmlSanitizer es una librería .NET para limpiar fragmentos y documentos HTML de construcciones que pueden provocar ataques XSS.
