Jeg Kit for Elementor < 3.1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'sg_content_number_prefix' Shortcode Attribute

Description

The Jeg Kit for Elementor – Powerful Addons for Elementor, Widgets & Templates for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sg_content_number_prefix' parameter in all versions up to, and including, 3.1.0 due to insufficient input sanitization and output escaping. 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.
