The Livemesh Addons for WPBakery Page Builder plugin for WordPress is vulnerable to a type of cyber attack known as Stored Cross-Site Scripting. This means that versions of the plugin up to, and including, 3.5 are not secure against malicious activity. Attackers with contributor-level access or higher, can exploit this vulnerability by injecting malicious web scripts into pages that can be executed when the page is opened by a user.
