xwiki-commons-xml is vulnerable to HTML Injection. The vulnerability exists because the HTMLDefinitions function in HTMLDefinitions.java does not properly disallow form-related tags in the HTML sanitizer, which allows an attacker to inject and execute malicious code such as {{html}}{{/html}} through the context of the XWiki.
