## What is CVE-2026-107746?

CVE-2026-107746 is a high-severity missing authorization vulnerability in teamfunnelkit FunnelKit – Funnel Builder Plugin for WooCommerce Checkout, published on 16 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The FunnelKit – Funnel Builder for WooCommerce Checkout plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.16.0.6 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve billing PII — including full name, street address, email address, and phone number — for any WooCommerce order on the site by submitting an enumerable sequential order ID. This is only exploitable on sites where a FunnelKit thank-you page exists that renders the [wfty_order_meta] or [wfty_order_total] shortcode.

Weakness: CWE-862 (Missing Authorization)
