• Severity: high (CVSS 7.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

The NotificationX – FOMO, Live Sales Notification, WooCommerce Sales Popup, GDPR, Social Proof, Announcement Banner & Floating Notification Bar plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via the 'nx-preview' POST parameter in all versions up to, and including, 3.2.0. This is due to insufficient input sanitization and output escaping when processing preview data. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute when a user visits a malicious page that auto-submits a form to the vulnerable site.
