## Technical details

The plugin fails to escape user-supplied input before reflecting it in an unauthenticated AJAX response served as HTML, enabling reflected XSS via the render_ifso_shortcodes endpoint. An attacker can craft a malicious URL that, when visited by a victim, executes arbitrary JavaScript with the victim's privileges and session context. The vulnerability affects versions 1.8 through 1.10.1; no authentication or user interaction beyond clicking a link is required.
