Kirki 6.2.1 - 6.2.5 - Unauthenticated Stored XSS via HTML Entity Decoding

Description

The plugin 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.
