Smart Popup permission collision permits unauthenticated administrator creation
Smart Popup by Supsystic through 1.12.0 merges controller permission maps in havePermissions() so that the popup module's administrator-only save restriction is overwritten. The unauthenticated wp_ajax_nopriv_save path accepts the generic pps_nonce included in a public subscription confirmation email and lacks a server-side role allowlist in createWpSubscriber(). An unauthenticated attacker who obtains that nonce can submit params[tpl][sub_wp_create_user_role]=administrator through popupControllerPps::save(), then trigger the saved confirmation flow to create a persistent administrator account with attacker-selected credentials.
