At a glance

CVE-2024-6836 is a medium-severity Missing Authorization vulnerability in the FunnelKit WordPress plugin, affecting versions <= 3.4.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 3.4.7; sites on affected versions should update now. Disclosed July 2024, reported by Lucio Sá.

Vulnerability Overview

The Funnel Builder for WordPress by FunnelKit – Customize WooCommerce Checkout Pages, Create Sales Funnels, Order Bumps & One Click Upsells plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on multiple functions in all versions up to, and including, 3.4.6. This makes it possible for authenticated attackers, with Contributor-level access and above, to update multiple settings, including templates, designs, checkouts, and other plugin settings.

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 interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in FunnelKit <= 3.4.6 takes an account at Contributor level or above. 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 FunnelKit the fix is 3.4.7: builds <= 3.4.6 are affected, anything from 3.4.7 onward is not.

Remediation

Update to version 3.4.7, 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: FunnelKit 3.4.7 closes this, and updating the plugin is the step that ends it.
