Vulnerability Overview

The Visual Composer Website Builder, Landing Page Builder, Custom Theme Builder, Maintenance Mode & Coming Soon Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's custom fields in all versions up to, and including, 45.6.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 45.7.0, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
