Because `display_name` is writable by any user on their own account through the core profile form, this makes it possible for authenticated attackers with Subscriber-level access and above to execute arbitrary shortcodes. Where the page is a users collection — an ordinary team or member-directory page — the shortcode runs in the request of every visitor, including unauthenticated ones. Requires a published page with a Kirki element whose dynamic content is bound to the `display_name` user field.","state":0,"publishedAt":"2026-10-10T07:41:47.748+00:00","modifiedAt":"2026-10-11T16:55:15.382+00:00","affected":[{"ecosystem":"Vendor product","name":"Kirki – Freeform Page Builder, Website Builder & Customizer","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"themeum\",\n                    \"product\": \"Kirki – Freeform Page Builder, Website Builder & Customizer\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"6.3.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/bed93040-a843-417e-89b4-5ab3cba788aa?source=cve","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/TheFrontend.php#L144","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L408","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L308","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L334","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/HelperFunctions.php#L1117","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Manager/PluginShortcode.php#L40","https://plugins.trac.wordpress.org/changeset?reponame=&new=3718900%40kirki%2Ftags%2F6.3.2&old=3697265%40kirki%2Ftags%2F6.3.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102291","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102291","identifiers":["CVE-2026-102291"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
