## Description

The If-So Dynamic Content plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'conversion' attribute of the ifso_conversion shortcode, the 'url' attribute of the ifso-redirect shortcode (shown to administrators when 'exclude_admins' is set), and the 'message' attribute of the ifso_hide_site_content shortcode in all versions up to, and including, 1.10.2. This is due to insufficient output escaping on user-supplied shortcode attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
