Popup Box – Create Countdown, Coupon, Video, Contact Form Popups < 4.9.8 - Missing Authorization to Unauthenticated Limited Options Update

Description

The Popup Box – Create Countdown, Coupon, Video, Contact Form Popups plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the deactivate_plugin_option() function in all versions up to, and including, 4.9.7. This makes it possible for unauthenticated attackers to update the 'ays_pb_upgrade_plugin' option with arbitrary data.
