Description
The Livemesh Addons for Elementor plugin for WordPress is vulnerable to unauthorized modification of data and Stored Cross-Site Scripting via plugin settings in all versions up to, and including, 9.0. This is due to missing authorization checks on the AJAX handler `lae_admin_ajax()` and insufficient output escaping on multiple checkbox settings fields. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in the plugin settings page that will execute whenever an administrator accesses the plugin settings page granted they can obtain a valid nonce, which can be leaked via the plugin's improper access control on settings pages.
