Essential Addons for Elementor < 5.9.15 - Contributor+ Store XSS via Widget URL

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the URL attributes of widgets 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.
