## Overview

The Kadence Blocks — Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Identity Block Inner Image Content in all versions up to, and including, 3.7.8.1 due to insufficient input sanitization and output escaping. 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. This vulnerability is only triggerable when the block's urlTransparent attribute is set to a non-empty value, as this is a required precondition for the vulnerable code path in build_html() to be reached.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
