The zipMoney(Zip Co) Payments Plugin for WooCommerce WordPress plugin before 2.4.0 does not perform any authorisation checks on one of its front-end request handlers, and does not restrict which option name a caller may supply, allowing unauthenticated users to delete arbitrary WordPress options. This can be used to destroy site and access control configuration, deactivate every installed zipMoney(Zip Co) Payments Plugin for WooCommerce WordPress plugin before 2.4.0, and take the site offline.
