CVE, Research URL: CVE-2026-3895
Home page URL: Security reports for WPBakery Page Builder Addons by Livemesh
Application: WPBakery Page Builder Addons by Livemesh
Published on: May 27, 2026
Research Description: The WPBakery Page Builder Addons by Livemesh plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `lvca_admin_ajax` AJAX action in all versions up to, and including, 3.9.4 due to missing authorization checks and insufficient input sanitization. The AJAX handler verifies a nonce but does not check user capabilities. This makes it possible for authenticated attackers with Subscriber-level access and above to modify plugin settings and inject malicious scripts that execute when administrators access the plugin settings page or when any user visits the frontend.
Affected versions: max 3.9.4.
Status: vulnerable
