What is CVE-2025-15380?

The NotificationX plugin for WordPress allows unauthenticated attackers to exploit a DOM-Based Cross-Site Scripting vulnerability. This occurs through the 'nx-preview' POST parameter, where the plugin fails to properly sanitize input and escape output while processing preview data. This inadequacy enables attackers to inject malicious web scripts into the application's pages. When a user visits a compromised page that auto-submits a form to the affected site, the injected scripts are executed, compromising the security of users' sessions and data.

Affected Version(s)

NotificationX – FOMO, Live Sales Notification, WooCommerce Sales Popup, GDPR, Social Proof, Announcement Banner & Floating Notification Bar 0 <= 3.2.0
