An issue exists in MediaWiki prior to 1.35.7, 1.36.x and 1.37.x prior to 1.37.3, and 1.38.x prior to 1.38.1. XSS can occur in configurations that allow a JavaScript payload in a username. After account creation, when it sets the page title to "Welcome" followed by the username, the username is not escaped: SpecialCreateAccount::successfulAction() calls ::showSuccessPage() with a message as second parameter, and OutputPage::setPageTitle() uses text().
