Gutenberg Blocks with AI Vulnerable to Stored Cross-Site Scripting

Summary

The Gutenberg Blocks with AI by Kadence WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'link' attribute of the plugin's blocks in all versions up to, and including, 3.2.36 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.
