The Infility Global WordPress plugin through 2.9.8 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin.

The Infility Global plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘set_type’ parameter in all versions up to, and including, 2.9.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Infility Global plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the infility_global_ajax function in all versions up to, and including, 2.9.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update plugin options and potentially break the site.
