W3 Total Cache < 2.8.2 - Subscriber+ Server-Side Request Forgery

Description

The plugin is vulnerable to unauthorized access of data due to a missing capability check on the is_w3tc_admin_page function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to obtain the plugin's nonce value and perform unauthorized actions, resulting in information disclosure, service plan limits consumption as well as making web requests to arbitrary locations originating from the web application that can be used to query information from internal services, including instance metadata on cloud-based applications.
