## Description

The If-So Dynamic Content plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the Dynamic Keyword Insertion (ifsoDKI) rendering of the 'render_ifso_shortcodes' AJAX action in all versions up to, and including, 1.10.3, due to insufficient sanitization and escaping. The DKI attributes are taken from the request, and the rendered values (for example the output of the 'time' type with a request-supplied 'format') are returned JSON-encoded without encoding HTML tags in a response served as HTML. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute if they can successfully trick a user into performing an action such as clicking on a crafted link.
