Summary
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.
Risk Assessment
The risk involves the possibility of injecting malicious scripts, which may lead to session theft, account takeover, or malware distribution among users.
Recommendation
It is recommended to update WPBakery Page Builder to a version newer than 8.6.1 and restrict access to shortcodes to trusted users only.
