The NotificationX – Live Sales Notification, WooCommerce Sales Popup, FOMO, Social Proof, Announcement Banner & Floating Notification Top Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's content settings for notifications in all versions up to, and including, 2.9.3 due to insufficient input sanitization and output escaping.
