Stored XSS in DiviGear Carousel WordPress Plugin

Publication date: 2026-10-20

Last updated on: 2026-10-20

Assigner: Wordfence

Description
The DiviGear Carousel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via update_license AJAX Action in all versions up to, and including, 5.2.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload executes when an administrator visits the DiviGear > Activation settings page, where the unsanitized stored value is echoed unescaped into a single-quoted HTML value attribute.

Executive Summary

The DiviGear Carousel WordPress plugin up to version 5.2.0 has a stored cross-site scripting (XSS) vulnerability. This flaw allows authenticated attackers with subscriber-level access or higher to inject malicious scripts into web pages. The issue occurs due to insufficient input sanitization and output escaping in the update_license AJAX action. When an administrator visits the DiviGear Activation settings page, the injected script executes because the stored value is echoed unescaped into an HTML attribute.

Detection Guidance

Check if the DiviGear Carousel plugin version 5.2.0 or lower is installed on your WordPress site. Log in as a subscriber or higher and inspect the DiviGear > Activation settings page for unsanitized input in the license field. Look for stored JavaScript payloads in page source or database entries.

Impact Analysis

An attacker could exploit this to inject malicious scripts into your WordPress site. These scripts could steal sensitive data like cookies or session tokens, redirect users to malicious sites, or perform actions on behalf of users. Since the payload executes when an admin visits the settings page, it could lead to complete site compromise if the admin's session is hijacked.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection principles and HIPAA's security requirements. If exploited, it may result in data breaches, leading to legal penalties, reputational damage, and loss of trust. Organizations must address this to maintain compliance with these regulations.

Mitigation Strategies

Update the DiviGear Carousel plugin to the latest version beyond 5.2.0 immediately. Remove any suspicious JavaScript payloads from the license field in DiviGear > Activation settings. Restrict subscriber-level access to only trusted users until patched.
