Finale Lite – Sales Countdown Timer & Discount for WooCommerce <= 2.19.0 - Authenticated (Contributor+) Stored DOM-Based Cross-Site Scripting via Countdown Timer

The Finale Lite – Sales Countdown Timer & Discount for WooCommerce plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the countdown timer in all versions up to, and including, 2.19.0 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.
