Extra Product Options for WooCommerce < 3.0.7 - Missing Authorization

Description

The Extra Product Options for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the epofw_get_data_based_on_cd and epofw_change_field_basedon_type() functions in versions up to, and including, 3.0.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to update fields.
