What the vulnerability does
01Description
The Happy Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘url’ attribute within the plugin's Gradient Heading widget in all versions up to, and including, 3.11.1 due to insufficient input sanitization and output escaping.
