The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to unauthenticated privilege escalation in versions up to and including 3.29.2. This is due to insecure form submission handling that accepts arbitrary form definitions from user input instead of securely loading them from the backend. When $_POST['_acf_form'] is an array (rather than a form ID), the validate_form() function bypasses database lookup and directly processes the attacker-controlled structure. The create_record() function preserves attacker-supplied record data if present, and the user action's run() function falls back to attacker-controlled field definitions from $form['fields'] when legitimate fields cannot be found. The role field's pre_update_value() validation reads $field['role_options'] from this attacker-controlled definition, allowing an attacker to specify ['administrator'] as an allowed role and bypass the security check. This makes it possible for unauthenticated attackers to create administrator accounts by injecting a custom form configuration with a spoofed role field.
