CVE-2026-18432: CWE-269 Improper Privilege Management in shabti Frontend Admin by DynamiApps
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.
