The WordLift – AI powered SEO – Schema plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the 'wl_config_plugin' AJAX action in all versions up to, and including, 3.54.0. This makes it possible for unauthenticated attackers to update the plugin's settings.

The WordLift WordPress plugin before 3.37.2 does not sanitise and escape its settings, allowing high privilege users such as admin to perform cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
