 "title": "Kirki <= 6.4.0 - Authenticated (Subscriber+) Arbitrary Shortcode Execution via User Profile Fields in Dynamic SEO Values",
 "description": "The Kirki plugin for WordPress is vulnerable to arbitrary shortcode execution via dynamic SEO values in all versions up to, and including, 6.4.0, due to user-editable values such as display names, user profile fields, term names and CMS fields being concatenated into the SEO title and description string that is passed to do_shortcode() without stripping shortcode brackets. This makes it possible for authenticated attackers with subscriber-level access and above to execute arbitrary shortcodes by placing them in their profile fields, when a page's SEO settings use those dynamic user values, for example on an author archive or user template.",
