CVE-2026-3895 Details
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.
A stored cross-site scripting vulnerability has been identified in the WPBakery Page Builder Addons by Livemesh plugin for WordPress, affecting all versions through 3.9.4. The vulnerability arises from missing authorization checks and inadequate input sanitization in the 'lvca_admin_ajax' AJAX action.
