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."}],"title":"Frontend Admin by DynamiApps <= 3.29.9 - Unauthenticated Privilege Escalation via 'item_id' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/01404fad-7b5a-485a-b557-c608fe25e6c9?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/actions/user.php#L680"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/actions/user.php#L565"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/classes/display.php#L1654"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/classes/display.php#L37"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.9/main/frontend/forms/classes/display.php#L1953"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/actions/user.php#L680"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/actions/user.php#L565"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L1654"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L37"},{"url":"https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L1953"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3633030%40acf-frontend-form-element&new=3633030%40acf-frontend-form-element"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"밥김국"}],"timeline":[{"time":"2026-07-30T20:18:41.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-15T15:30:21.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-18T19:27:30.594573Z","id":"CVE-2026-18432","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-18T19:27:39.511Z"}}]}}
