{"id":"CVE-2026-12409","state":"PUBLISHED","title":"Landing Page Builder <= 1.5.3.6 - Cross-Site Request Forgery to ulpb_admin_data AJAX Action","description":"The Landing Page Builder – Coming Soon page, Maintenance Mode, Lead Page, WordPress Landing Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.3.6. This is due to missing or incorrect nonce validation on the ulpb_admin_ajax function. This makes it possible for unauthenticated attackers to create, update, retitle, or change the post status, slug, and type of arbitrary posts and write ULPB_DATA post meta via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This attack requires the victim to hold an editor-level or administrator session, as the wp_ajax_ulpb_admin_data action enforces a capability check that the forged request must satisfy by inheriting the logged-in user's session cookies.","publishedAt":"2026-07-16T02:30:56.243Z","updatedAt":"2026-07-17T12:37:27.474Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["umarbajwa Landing Page Builder – Coming Soon page, Maintenance Mode, Lead Page, WordPress Landing Pages"],"affected":[{"vendor":"umarbajwa","product":"Landing Page Builder – Coming Soon page, Maintenance Mode, Lead Page, WordPress Landing Pages","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.5.3.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a2b2dd36-eca8-4d80-80f5-783f9402dd3c?source=cve","https://plugins.trac.wordpress.org/browser/page-builder-add/tags/1.5.3.6/admin/classes/ajax-requests-class.php#L111","https://plugins.trac.wordpress.org/browser/page-builder-add/tags/1.5.3.6/admin/classes/ajax-requests-class.php#L19","https://plugins.trac.wordpress.org/browser/page-builder-add/tags/1.5.3.5/admin/classes/ajax-requests-class.php#L111","https://plugins.trac.wordpress.org/browser/page-builder-add/tags/1.5.3.5/admin/classes/ajax-requests-class.php#L19","https://plugins.trac.wordpress.org/changeset?reponame=&old=3444409%40page-builder-add&new=3444409%40page-builder-add"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12409.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12409","state":"PUBLISHED","datePublished":"2026-07-16T02:30:56.243Z","dateUpdated":"2026-07-17T12:37:27.474Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-16T14:43:41.329Z"},"containers":{"cna":{"title":"Landing Page Builder <= 1.5.3.6 - Cross-Site Request Forgery to ulpb_admin_data AJAX Action","descriptions":[{"lang":"en","value":"The Landing Page Builder – Coming Soon page, Maintenance Mode, Lead Page, WordPress Landing Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.3.6.
