SMS Alert shared OTP state permits unauthenticated privilege escalation
SMS Alert through 3.9.7 uses shared OTP-verification session state across multiple supported form integrations. The official 3.9.8 source replaces the common sa_mobile_verified flag with integration-specific verification flags and tightens WooCommerce phone and session matching, preventing verification in one flow from satisfying another security boundary.
