CVE-2026-1722

The WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.0. This is due to the plugin not implementing authorization checks in the `wcfm-refund-requests-form` AJAX controller. This makes it possible for unauthenticated attackers to create arbitrary refund requests for any order ID and item ID, potentially leading to financial loss if automatic refund approval is enabled in the plugin settings.

The following products are affected by CVE-2026-1722 vulnerability.
