What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The Kirki WordPress plugin before 6.3.2 does not prevent shortcodes held in comments from being executed when it renders them, and displays comments regardless of their moderation status, allowing unauthenticated visitors to run shortcodes registered on the site and to read private custom fields of the page being viewed.
