WCFM Marketplace <= 3.7.0 - Insecure Direct Object Reference to Unauthenticated Arbitrary Refund Request Creation

Missing Authorization
CVE CVE-2026-1722
CVSS Medium (5.3)
Publicly Published February 9, 2026

Researcher Gibran Abdillah
Description

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.
