Royal Elementor Addons and Templates <= 1.7.1017 - Authenticated (Contributor+) Stored Cross-Site Scripting

The Royal Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Countdown widget display_message_text parameter in all versions up to, and including, 1.7.1017 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.
