What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The Synchrony Financing WordPress plugin before 1.1.2 does not properly authorise requests to one of its REST routes that modifies WooCommerce orders, allowing unauthenticated attackers to reassign any order to an account they control, tamper with its details, and read the associated customer's personal data.
