Official description

The Kirki WordPress plugin before 6.3.0 does not hold back every spelling of the HTML entities it decodes when rendering, allowing unauthenticated users to store JavaScript in a comment which then runs in the session of anyone viewing a page that displays it, including an administrator, and on every page of the site when its header or footer is built to show comments.
