HT Slider for Elementor <= 1.7.4 - Authenticated (Contributor+) Stored Cross-Site Scripting

The HT Slider for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slide_title' parameter in all versions up to, and including, 1.7.4 due to insufficient input sanitization and output escaping in JavaScript. 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.
