Multiple FunnelKit plugins are vulnerable to Sensitive Information Exposure via the wfgetcookie shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including authentication cookies of other site users, which may make privilege escalation possible. Please note both FunnelKit – Funnel Builder for WooCommerce Checkout AND FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce are affected by this.

Subscriber Broken Authentication in FunnelKit Automations <= 3.7.3 versions.

The FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.6.4.1 via the '/wc-coupons/' REST API endpoint. This is due to the endpoint being marked as a public API (publicapi = true), which results in the endpoint being registered with permissioncallback => 'returntrue', bypassing all authentication and capability checks. This makes it possible for unauthenticated attackers to extract sensitive data including all WooCommerce coupon codes, coupon IDs, and expiration status.

The FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.6.4.1. This is due to the plugin not properly verifying that a user is authorized to perform administrative actions in the bwfantestemail AJAX handler. The nonce used for verification is publicly exposed to all visitors (including unauthenticated users) via the frontend JavaScript localization, and the checknonce() function accepts low-privilege authenticated users who possess this nonce. This makes it possible for authenticated attackers, with Subscriber-level access and above, to send arbitrary emails from the site with attacker-controlled subject and body content.
