Publication date: 2026-09-25

Last updated on: 2026-09-25

Assigner: Wordfence

Description
The CSS & JavaScript Toolbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's cjtoolbox shortcode in all versions up to, and including, 12.0.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the CSS & JavaScript Toolbox WordPress plugin. It allows authenticated attackers with contributor-level access or higher to inject malicious scripts via the plugin's cjtoolbox shortcode. The flaw exists due to insufficient input sanitization and output escaping on user-supplied attributes.

Detection Guidance

Check WordPress sites for the CSS & JavaScript Toolbox plugin versions up to 12.0.6. Review pages using the cjtoolbox shortcode for suspicious scripts in attributes. Use security plugins like Wordfence to scan for stored XSS attempts.

Impact Analysis

An attacker could inject malicious scripts into pages on your WordPress site. When users access these pages, the scripts execute, potentially stealing sensitive data like cookies or session tokens, redirecting users to malicious sites, or performing actions on their behalf.

Compliance Impact

This vulnerability could lead to data breaches, compromising personal or sensitive data. For GDPR, it may result in unauthorized access to user data, violating principles of data protection and user consent. For HIPAA, it could expose protected health information, leading to compliance violations and legal penalties.

Mitigation Strategies

Update the CSS & JavaScript Toolbox plugin to the latest version. Remove or restrict contributor-level access to untrusted users. Implement web application firewalls to block XSS payloads. Monitor pages using the cjtoolbox shortcode for unexpected scripts.
