Vulnerability Overview

The Breeze Cache plugin for WordPress is vulnerable to Cache Poisoning in all versions up to, and including, 2.5.14. This is due to unkeyed tracking parameters. This makes it possible for unauthenticated attackers to poison cached responses.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-345: Insufficient Verification of Data Authenticity

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.

Remediation

Update to version 2.5.15, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Breeze Cache 2.5.15 closes this, and updating the plugin is the step that ends it.
