## Description

The The Plus Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Wrapper Link extension's link URL in all versions up to, and including, 6.5.3, due to insufficient output escaping. esc_url() keeps HTML entities such as an encoded quote, and the frontend script concatenated the decoded URL into an anchor's HTML before appending it. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute when a user clicks the wrapped element.
