XML Injection vulnerability in joshnuss xml_builder (XmlBuilder module) allows Content Spoofing, XML Injection.

This vulnerability is associated with program files lib/xml_builder.ex and program routines XmlBuilder.generate/1, XmlBuilder.generate/2, XmlBuilder.element/1, XmlBuilder.element/2, XmlBuilder.element/3.

Element names, attribute names, and doctype identifiers are interpolated verbatim into the serialized XML output without validation or escaping of structural characters (<, >, ', ', &). An attacker who can influence a name argument (for example, an element name derived from a JSON object key or an HTTP form field name) can inject arbitrary XML markup including extra elements, comments, and event-handler attributes into the output document.

This issue affects xml_builder: from 0.0.1 before 2.4.1.
