Descripción
The Gutenberg Blocks with AI by Kadence WP – Page Builder Features plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘redirectURL’ parameter in all versions up to, and including, 3.5.10 due insufficient input sanitization output escaping. This makes it possible authenticated attackers, Contributor-level access above, inject arbitrary web scripts pages that will execute whenever a user accesses an injected page.
