{"id":"CVE-2026-18432","state":"PUBLISHED","title":"Frontend Admin by DynamiApps <= 3.29.9 - Unauthenticated Privilege Escalation via 'item_id' Parameter","description":"The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.29.9. The vulnerability exists because `ActionUser::conditions_logic()` gates the `current_user_can('edit_user', $user_id)` authorization check behind an `is_numeric()` test, causing the check to be skipped entirely when `$user_id` is a non-numeric string — a condition that can be induced by passing a crafted value such as `1one` through the unvalidated `item_id` parameter of the unauthenticated `wp_ajax_nopriv_frontend_admin/forms/change_form` AJAX endpoint. This makes it possible for attackers to escalate privileges to administrator by obtaining a server-signed `_acf_objects` payload carrying the non-numeric user ID, which WordPress subsequently coerces to integer 1 (the default administrator), allowing the attacker to overwrite that account's password or email address. Exploitation by unauthenticated users requires a public-facing frontend user form to be configured; in all other cases a subscriber-level account is sufficient.","publishedAt":"2026-08-16T04:24:49.468Z","updatedAt":"2026-08-18T19:27:39.511Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["shabti Frontend Admin by DynamiApps"],"affected":[{"vendor":"shabti","product":"Frontend Admin by DynamiApps","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.29.9","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/01404fad-7b5a-485a-b557-c608fe25e6c9?source=cve","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/actions/user.php#L680","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/actions/user.php#L565","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/classes/display.php#L1654","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/classes/display.php#L37","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/classes/display.php#L1953","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/actions/user.php#L680","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/actions/user.php#L565","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L1654","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L37","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L1953","https://plugins.trac.wordpress.org/changeset?reponame=&old=3633030%40acf-frontend-form-element&new=3633030%40acf-frontend-form-element"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/18xxx/CVE-2026-18432.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-18432","state":"PUBLISHED","datePublished":"2026-08-16T04:24:49.468Z","dateUpdated":"2026-08-18T19:27:39.511Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-30T20:03:25.244Z"},"containers":{"cna":{"title":"Frontend Admin by DynamiApps <= 3.29.9 - Unauthenticated Privilege Escalation via 'item_id' Parameter","descriptions":[{"lang":"en","value":"The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.29.9.
