{"id":"CVE-2026-4124","state":"PUBLISHED","title":"Ziggeo <= 3.1.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'ziggeo_ajax' AJAX Action","description":"The Ziggeo plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.1.1. The wp_ajax_ziggeo_ajax handler  only verifies a nonce (check_ajax_referer) but performs no capability checks via current_user_can(). Furthermore, the nonce ('ziggeo_ajax_nonce') is exposed to all logged-in users on every page via the wp_head and admin_head hooks . This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke multiple administrative operations including: saving arbitrary translation strings (translations_panel_save_strings via update_option('ziggeo_translations')), creating/updating/deleting event templates (event_editor_save_template/update_template/remove_template via update_option('ziggeo_events')), modifying SDK application settings (sdk_applications operations), and managing notifications (notification_handler via update_option('ziggeo_notifications')).","publishedAt":"2026-04-09T02:25:04.372Z","updatedAt":"2026-04-13T15:15:09.635Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","source":"Wordfence"},"assigner":"Wordfence","products":["oliverfriedmann Ziggeo"],"affected":[{"vendor":"oliverfriedmann","product":"Ziggeo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/15477c00-0764-4850-8bce-d65b6b1cbe4c?source=cve","https://plugins.trac.wordpress.org/browser/ziggeo/trunk/core/ajax.php#L31","https://plugins.trac.wordpress.org/browser/ziggeo/tags/3.1.1/core/ajax.php#L31","https://plugins.trac.wordpress.org/browser/ziggeo/trunk/admin/page_translations_ajax.php#L13","https://plugins.trac.wordpress.org/browser/ziggeo/tags/3.1.1/admin/page_translations_ajax.php#L13","https://plugins.trac.wordpress.org/browser/ziggeo/trunk/admin/page_editor_events_ajax.php#L13","https://plugins.trac.wordpress.org/browser/ziggeo/tags/3.1.1/admin/page_editor_events_ajax.php#L13","https://plugins.trac.wordpress.org/browser/ziggeo/trunk/admin/page_sdk_ajax.php#L8","https://plugins.trac.wordpress.org/browser/ziggeo/tags/3.1.1/admin/page_sdk_ajax.php#L8","https://plugins.trac.wordpress.org/browser/ziggeo/trunk/core/header.php#L67","https://plugins.trac.wordpress.org/browser/ziggeo/tags/3.1.1/core/header.php#L67","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3494290%40ziggeo&new=3494290%40ziggeo&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4124.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4124","state":"PUBLISHED","datePublished":"2026-04-09T02:25:04.372Z","dateUpdated":"2026-04-13T15:15:09.635Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-13T13:43:23.239Z"},"containers":{"cna":{"title":"Ziggeo <= 3.1.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Modification via 'ziggeo_ajax' AJAX Action","descriptions":[{"lang":"en","value":"The Ziggeo plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.1.1.
