WPBakery Page Builder <= 8.6.1 - Stored Cross-Site Scripting via vc_custom_heading Shortcode

WPBakery Page Builder <= 8.6.1 - Stored Cross-Site Scripting via vc_custom_heading Shortcode

The WPBakery Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the vc_custom_heading shortcode in all versions up to, and including, 8.6.1. This is due to insufficient restriction of allowed HTML tags and improper sanitization of user-supplied attributes in the font_container parameter. This makes it possible for authenticated attackers with contributor-level access or higher to inject arbitrary web scripts in posts that will execute whenever a user accesses an injected page via the vc_custom_heading shortcode with malicious tag and text attributes granted they have access to use WPBakery shortcodes.

CWE-80 Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.
