{"cve":"CVE-2026-18432","nvd":{"published":"2026-08-16T05:16:48.307","modified":"2026-08-20T12:48:10.287","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-269"],"references":["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/actions/user.php#L680","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#L1953","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.29.3/main/frontend/forms/classes/display.php#L37"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-18432","score":0.00837,"percentile":0.57772,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
