{"id":"CVE-2026-9018","state":"PUBLISHED","title":"Easy Elements for Elementor – Addons & Website Templates <= 1.4.5 - Unauthenticated Privilege Escalation via 'custom_meta' Parameter","description":"The Easy Elements for Elementor – Addons & Website Templates plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.4.5 via the `easyel_handle_register()` function. This is due to the `wp_ajax_nopriv_eel_register` AJAX handler iterating the attacker-controlled `custom_meta` POST array and writing every supplied key-value pair to the newly created user's meta via `update_user_meta()` without any key whitelist or blocklist, allowing the `wp_capabilities` user meta key to be overwritten after `wp_insert_user()` has already assigned a safe role. This makes it possible for unauthenticated attackers to register a new account with full administrator-level privileges by supplying `custom_meta[wp_capabilities][administrator]=1`. Exploitation requires that user registration is enabled on the site and that at least one page exposes the Login/Register widget, which publishes the required `easy_elements_nonce` into the page DOM where it can be retrieved by any unauthenticated visitor via a simple GET request.","publishedAt":"2026-05-22T04:29:04.565Z","updatedAt":"2026-05-22T12:19:20.970Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["themewant Easy Elements for Elementor – Addons & Website Templates"],"affected":[{"vendor":"themewant","product":"Easy Elements for Elementor – Addons & Website Templates","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f1de4899-532a-4558-bff0-f4610bfdd49d?source=cve","https://plugins.trac.wordpress.org/browser/easy-elements/tags/1.4.5/widgets/login-register/class.login-register.php#L65","https://plugins.trac.wordpress.org/browser/easy-elements/tags/1.4.5/widgets/login-register/class.login-register.php#L128","https://plugins.trac.wordpress.org/browser/easy-elements/tags/1.4.5/widgets/login-register/class.login-register.php#L9","https://plugins.trac.wordpress.org/browser/easy-elements/tags/1.4.5/includes/Utils/Enqueue.php#L200"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9018.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9018","state":"PUBLISHED","datePublished":"2026-05-22T04:29:04.565Z","dateUpdated":"2026-05-22T12:19:20.970Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-19T14:38:27.978Z"},"containers":{"cna":{"title":"Easy Elements for Elementor – Addons & Website Templates <= 1.4.5 - Unauthenticated Privilege Escalation via 'custom_meta' Parameter","descriptions":[{"lang":"en","value":"The Easy Elements for Elementor – Addons & Website Templates plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.4.5 via the `easyel_handle_register()` function.
