Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.10.2 and 5.5.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Craft Commerce Order details. Malicious JavaScript can be injected via the Shipping Method Name, Order Reference, or Site Name. When a user opens the order details slideout via a double-click on the order index page, the injected payload executes. This vulnerability is fixed in 4.10.2 and 5.5.3.
