CWE: CWE-79 \u2014 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

Code:
    public function prepare($config, $context)
    {
        $this->htmlDefinition = $config->getHTMLDefinition();
        // Even though this might fail, some unit tests ignore this and
        // still test checkNeeded, so be careful. Maybe get rid of that
        // dependency.
        $result = $this->checkNeeded($config);
        if ($result !== false) {
            return $result;
        }
        $this->currentNesting =& $context->get('CurrentNesting');
        $this->currentToken   =& $context->get('CurrentToken');
        $this->inputZipper    =& $context->get('InputZipper');
        return false;
    }
