Sina Extension for Elementor (Slider, Gallery, Form, Modal, Data Table, Tab, Particle, Free Elementor Widgets & Elementor Templates) < 3.7.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via `Fancy Text Widget` And `Countdown Widget`

Description

The Sina Extension for Elementor (Header Builder, Footer Builter, Theme Builder, Slider, Gallery, Form, Modal, Data Table Free Elementor Widgets & Elementor Templates) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `Fancy Text Widget` And `Countdown Widget` DOM attributes in all versions up to, and including, 3.7.0 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.
