The Quiz Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `vc_quizmaker` shortcode in all versions up to, and including, 6.7.1.7 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Note: This vulnerability requires WPBakery Page Builder to be installed and active
