ShopLentor – WooCommerce Builder for Elementor & Gutenberg +20 Modules – All in One Solution (formerly WooLentor) < 3.1.1 - Authenticated (Contributor+) Stored DOM-Based Cross-Site Scripting via Flash Sale Countdown Module

Description

The ShopLentor – WooCommerce Builder for Elementor & Gutenberg +20 Modules – All in One Solution (formerly WooLentor) plugin for WordPress is vulnerable to a Stored DOM-Based Cross-Site Scripting via the plugin's Flash Sale Countdown module in all versions up to, and including, 3.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
