No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Livemesh Addons for Beaver Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the labb_admin_ajax AJAX action in all versions up to, and including, 3.9.2 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.
