Infility Global <= 2.9.8 - Authenticated (Subscriber+) Missing Authorization to Plugin Options Update

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.
