Summary

The Kirki WordPress plugin before 6.3.2 does not prevent shortcodes held in comments from being executed when it renders them. It also displays comments regardless of their moderation status, so an unauthenticated visitor can run shortcodes registered on the site and read private custom fields of the page being viewed. The flaw is tracked as CWE-74.
