Description
The NGINX Cache Optimizer plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'nginxcacheoptimizer-blacklist-update' AJAX action in all versions up to, and including, 1.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to add URLs to the Exclude URLs From Dynamic Caching setting.
