Advisory
Source description from Wordfence Intelligence, credited to Dave Jong.
The WooCommerce - PDF Vouchers plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on several functions like 'woo_vou_trigger_upgrades', 'woo_vou_admin_run_v430_udater_script', 'woo_vou_activate_license', 'woo_vou_generate_system_log' and many more in all versions up to, and including 4.9.4. This makes it possible for unauthenticated attackers to perform several actions that should only be performed by admins.
