Subscriber-to-Administrator escalation via arbitrary option update
Published Mar 27, 2025 · Updated Apr 28, 2026
Missing authorization in WPC Smart Upsell Funnel for WooCommerce 3.0.4 and earlier allows remote authenticated users to gain Administrator access. The ajax_import_export_save() handler accepts attacker-controlled option names and values and passes them to update_option() without a capability check. Subscriber-level access is sufficient to change default_role to administrator and enable registration, so a newly registered account receives administrative privileges.
