Input validation vulnerability in WooCommerce 3.6.5

The WooCommerce plugin for WordPress is a program people can use to create an online store. Unfortunately, it has been found to have a security issue in versions up to 3.6.4. This issue allows attackers to add their own code to a file which they can then trick an administrator into uploading to the product description on the online store. To do this, they must be able to trick the administrator into clicking on a link.
