Vulnerability Overview

The Kadence WooCommerce Email Designer plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.5.19. This makes it possible for unauthenticated attackers to elevate their privileges.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-266: Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.

Remediation

Update to version 1.5.19.1, 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: Kadence WooCommerce Email Designer 1.5.19.1 closes this, and updating the plugin is the step that ends it.
