Last updated on: 2026-01-20

Assigner: Wordfence

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.

Executive Summary

This vulnerability is a DOM-Based Cross-Site Scripting (XSS) issue in the NotificationX WordPress plugin (up to version 3.2.0). It occurs because the plugin does not properly sanitize or escape input from the 'nx-preview' POST parameter. This allows unauthenticated attackers to inject malicious scripts that execute when a user visits a page that auto-submits a form to the vulnerable site.

Impact Analysis

The vulnerability can allow attackers to execute arbitrary scripts in the context of the affected website, potentially leading to theft of user data, session hijacking, defacement, or other malicious actions without requiring user interaction or authentication.

Compliance Impact

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts via DOM-Based Cross-Site Scripting due to insufficient input sanitization and output escaping. This could lead to unauthorized access or manipulation of user data, potentially impacting compliance with data protection regulations such as GDPR and HIPAA by compromising data integrity and user privacy.
