WP Fastest Cache 0.8.7.7 - 1.5.0 - Unauthenticated Cache Poisoning via Unkeyed Tracking Parameters

Summary

The WP Fastest Cache WordPress plugin before 1.5.1 does not include a set of tracking-related query parameters in its page-cache key while still caching pages requested with them, allowing unauthenticated attackers to have a page rendered under their own request context stored under, and served from, the clean URL's cache entry to every subsequent visitor.
