Technical details

The WPBakery Page Builder Addons by Livemesh plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the `[lvca_carousel]` and `[lvca_posts_carousel]` shortcodes. Specifically, shortcode attributes are processed using `wp_json_encode()` and placed into single-quoted `data-settings` HTML attributes without the use of `esc_attr()`. This allows an authenticated attacker with Contributor-level permissions or higher to break out of the HTML attribute by injecting single quotes and execute arbitrary JavaScript in the context of a user's browser. The vulnerability affects all versions up to and including 3.9.4.
