{"id":"CVE-2026-12472","state":"PUBLISHED","title":"Kirki <= 6.0.11 - Missing Authorization to Unauthenticated Arbitrary Email Content Injection (Mail Relay / Phishing) via 'emailBody' and 'emailSubject' Parameters","description":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.11. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to send arbitrary HTML-injected emails — including phishing messages embedding a real, valid WordPress password-reset URL for the targeted user — to any registered user via the site's own mail server, abusing its SPF/DKIM reputation. The attacker-controlled emailSubject parameter is passed to wp_mail() with only sanitize_text_field() applied, while emailBody 'text' items are concatenated raw into the HTML email body with no escaping, and 'chip' items can include the genuine WordPress password-reset link for the targeted account.","publishedAt":"2026-07-02T08:33:07.265Z","updatedAt":"2026-07-02T14:52:43.310Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/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":"6.0.11","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/af01964f-018d-4d19-8627-8889877db105?source=cve","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.9/ComponentLibrary/controller/CompLibFormHandler.php#L342","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.9/ComponentLibrary/controller/CompLibFormHandler.php#L441","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.9/ComponentLibrary/controller/CompLibFormHandler.php#L49","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.9/ComponentLibrary/controller/ElementGenerator.php#L219","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3584702%40kirki&new=3584702%40kirki&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12472.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12472","state":"PUBLISHED","datePublished":"2026-07-02T08:33:07.265Z","dateUpdated":"2026-07-02T14:52:43.310Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-16T20:16:45.315Z"},"containers":{"cna":{"title":"Kirki <= 6.0.11 - Missing Authorization to Unauthenticated Arbitrary Email Content Injection (Mail Relay / Phishing) via 'emailBody' and 'emailSubject' Parameters","descriptions":[{"lang":"en","value":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.11.
