aThemes Addons for Elementor < 1.1.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Call To Action Widget

Description

The aThemes Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Call To Action widget in versions up to, and including, 1.1.5 due to insufficient input sanitization and output escaping on user-supplied values. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
