  • Shopify is a complete commerce platform that lets you start, grow, and manage a business. It has a protected atom feed, which is similar to RSS. These can be protected by a password.

  • Overall, this was a really simple bug; just a lack of auth on an endpoint. Sometimes, accessing data in unexpected ways has access control problems. This reminds me of a DropBox vulnerability from a 2020.
