The Amazon Products to WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wcta2w_get_amazon_product_callback() function in all versions up to, and including, 1.2.7. This makes it possible for unauthenticated attackers to create new produces.
