Technical Analysis
CVE-2026-100145 is an incorrect authorization vulnerability (CWE-863) in the Synchrony Financing WordPress plugin before version 1.1.2. The vulnerability exists because the plugin does not properly authorize requests to a REST route that modifies WooCommerce orders. Exploitation enables unauthenticated attackers to reassign any order to an account they control, tamper with order details, and read the personal data of the customer linked to the order.
Potential Impact
An attacker can gain unauthorized access to and control over WooCommerce orders, including reassigning orders to attacker-controlled accounts and viewing sensitive customer personal data. This can lead to privacy violations and potential fraud or abuse of order processing.
