AffiliateX 1.0.0 - 1.3.9.3 - Authenticated (Subscriber+) Missing Authorization to Stored Cross-Site Scripting via save_customization_settings

The AffiliateX – Amazon Affiliate Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_customization_settings AJAX action in versions 1.0.0 to 1.3.9.3.
