Miggo AIRoot Cause Analysis

The vulnerability stems from the unescaped 'highlight' parameter being passed to the template engine in BackendBaseAction::execute. The GitHub patch adds strip_tags() sanitization to this parameter, confirming that the lack of input filtering in the original code (via $this->getParameter('highlight')) was the vulnerable path. The function's role in processing user input for template rendering directly correlates with the XSS vulnerability described.
