Miggo AIRoot Cause Analysis
The vulnerability stemmed from missing HTML attribute sanitization in XWiki's rendering components. The commit introduces HTMLElementSanitizer across multiple renderers (XHTML, HTML5, AnnotatedHTML) and modifies XHTMLWikiPrinter to validate attributes. The affected functions are the rendering entry points that process HTML elements/attributes. The patch explicitly adds sanitization to these components, indicating they were previously vulnerable. Test file changes show attributes being prefixed with 'data-xwiki-translated-attribute-' when disallowed, proving the lack of prior validation.
