This makes it possible for authenticated attackers with Sales Representative-level access and above to upsert their own contact row to point to an Administrator's user ID, then invoke the v4 email-test endpoint (`POST /gh/v4/emails/test`) — also accessible to the Sales Representative role via the `send_emails` capability — to generate an `{auto_login_url}` one-time permissions key bound to the rebound contact, and consume that link to call `wp_set_auth_cookie()` and gain a fully authenticated session as the WordPress Administrator."
