{"schema":"threatline.record/2","record":{"id":"CVE-2026-102291","aliases":[],"summary":"Kirki – Freeform Page Builder, Website Builder & Customizer <= 6.3.1 - Authenticated (Subscriber+) Arbitrary Shortcode Execution via 'display_name'","details":"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.","categories":["Unclassified"],"product":"Kirki – Freeform Page Builder, Website Builder & Customizer","vendor":"themeum","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102291","source_modified_at":"2026-10-11T16:55:15.382Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Kirki – Freeform Page Builder, Website Builder & Customizer","vendor":"themeum","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.3.1","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00304,"percentile":0.22021,"score_date":"2026-10-23"},"published_at":"2026-10-10T07:41:47.748Z","modified_at":"2026-10-11T16:55:15.382Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102291","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-11T16:55:15.382Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102291","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/bed93040-a843-417e-89b4-5ab3cba788aa?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/TheFrontend.php#L144"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L408"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L308"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L334"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/HelperFunctions.php#L1117"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Manager/PluginShortcode.php#L40"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3718900%40kirki%2Ftags%2F6.3.2&old=3697265%40kirki%2Ftags%2F6.3.1"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-11T16:37:18.881293Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-11T16:55:15.382Z","content_hash":"821f0733dab11a3f02316a99e24eb4bf43975fb38f26865b400f7349137ec563"}}
