The Plus Addons for Elementor <= 5.6.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Countdown Widget

The The Plus Addons for Elementor – Elementor Addons, Page Templates, Widgets, Mega Menu, WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Countdown' widget in all versions up to, and including, 5.6.1 due to insufficient input sanitization and output escaping on user supplied 'text_days' attribute. 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.
