Craft Commerce is an ecommerce platform for Craft CMS. In versions from 4.0.0-RC1 to 4.10.0 and from 5.0.0 to 5.5.1, there is a Stored XSS via Product Type names. The name is not sanitized when displayed in user permissions settings. The vulnerable input (source) is in Commerce (Product Type settings), but the sink is in CMS user permissions settings. This issue has been patched in versions 4.10.1 and 5.5.2.
