Rolo Slider <= 1.0.9 - Missing Authorization to Authenticated(Subscriber+) Settings Change

Description

The Rolo Slider plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ajax_callback' function in all versions up to, and including, 1.0.9. This makes it possible for authenticated attackers, with subscriber access and above, to modify the plugin's settings via the import functionality.
