FunnelKit Automations vulnerabilities

There is a broken authentication issue for subscribers in FunnelKit Automations versions <= 3.7.3.

The FunnelKit Automations plugin for WordPress and WooCommerce up to 3.6.4.1 is vulnerable to Missing Authorization in the bwfan_test_email AJAX handler. The nonce is publicly exposed to all visitors, and check_nonce() accepts low-privilege authenticated users. This allows authenticated attackers with Subscriber-level access to send arbitrary emails from the site.

The FunnelKit Automations plugin for WordPress and WooCommerce in versions up to and including 3.6.4.1 is vulnerable to Sensitive Information Exposure via the '/wc-coupons/' REST API endpoint. The endpoint is marked as public (public_api = true) and registered with permission_callback => '__return_true', bypassing authentication and capability checks. This allows unauthenticated attackers to extract WooCommerce coupon codes, coupon IDs, and expiration status.
