  • Severity: medium-risk
  • Status: Fixed
  • Publication: June 18, 2025

The WPBakery Page Builder plugin for WordPress is at risk of a type of cyber attack known as Stored Cross-Site Scripting. This can happen through the plugin’s Grid Builder feature in all versions up to 8.4.1. The issue is caused by not properly filtering and securing user-provided information, allowing attackers with certain levels of access to insert harmful code onto pages. This code can then run when a user visits the affected page.
