Vulnerability Overview

Plugin Settings Change leading to Cross-Site Scripting (XSS) vulnerability in Cloudways Breeze plugin <= 2.0.2 on WordPress allows users with a subscriber or higher user role to execute any of the wp_ajax_* actions in the class Breeze_Configuration which includes the ability to change any of the plugin's settings including CDN setting which could be further used for XSS attack.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-862: Missing Authorization

Reaching this weakness in Breeze Cache <= 2.0.2 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Breeze Cache the fix is 2.0.3: builds <= 2.0.2 are affected, anything from 2.0.3 onward is not.

Remediation

Update to version 2.0.3, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Breeze Cache 2.0.3 closes this, and updating the plugin is the step that ends it.
