The PQ Addons – Creative Elementor Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widget attributes in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping on the html_tag parameter in the PQ Section Title widget. 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.
