The YS LeadGen plugin for WordPress is vulnerable to authorization bypass and Stored Cross-Site Scripting via multiple AJAX endpoints in all versions up to, and including, 2.1.4 due to missing capability checks on popup management actions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary popups and inject malicious JavaScript that executes when the popup is displayed, leading to Stored XSS.
