CVE-2026-1722WCFM Marketplace <= 3.7.0 - Insecure Direct Object Reference to Unauthenticated Arbitrary Refund Request Creation
Medium 5.3
In plain English
A medium-severity missing authorization in WCFM Marketplace – Multivendor Marketplace for WooCommerce from wclovers. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 26% of all known vulnerabilities).
Official 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.
