{"id":"CVE-2026-102291","state":"PUBLISHED","title":"Kirki – Freeform Page Builder, Website Builder & Customizer <= 6.3.1 - Authenticated (Subscriber+) Arbitrary Shortcode Execution via 'display_name'","description":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 6.3.1 This is due to the plugin substituting a user's `display_name` into the composed page markup unfiltered and then running the whole result through `do_shortcode()` in `TheFrontend::replace_content()`. 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.","publishedAt":"2026-10-10T07:41:47.748Z","updatedAt":"2026-10-11T16:55:15.382Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themeum Kirki – Freeform Page Builder, Website Builder & Customizer"],"affected":[{"vendor":"themeum","product":"Kirki – Freeform Page Builder, Website Builder & Customizer","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.3.1","versionType":"semver"}]}],"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"],"weaknesses":["CWE-74"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/102xxx/CVE-2026-102291.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-102291","state":"PUBLISHED","datePublished":"2026-10-10T07:41:47.748Z","dateUpdated":"2026-10-11T16:55:15.382Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-28T20:34:15.636Z"},"containers":{"cna":{"title":"Kirki – Freeform Page Builder, Website Builder & Customizer <= 6.3.1 - Authenticated (Subscriber+) Arbitrary Shortcode Execution via 'display_name'","descriptions":[{"lang":"en","value":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 6.3.1 This is due to the plugin substituting a user's `display_name` into the composed page markup unfiltered and then running the whole result through `do_shortcode()` in `TheFrontend::replace_content()`.
