Description
The Kadence Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Navigation Link block's 'imageRatio' attribute in versions 3.3.0 up to, and including, 3.7.11 due to insufficient output escaping when the block is rendered with an image. 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.
