Vulnerability details
The vulnerability allows a remote user to read internal staff comments on invoices, shipments and credit memos associated with their own orders.
The vulnerability exists due to missing storefront-visibility filtering in Mage_Rss_Model_Resource_Order::getAllCommentCollection() when building the customer order-status RSS feed. A remote user can open /rss/order/status through their order's feed link to read comments that staff marked as not visible on the storefront.
Both RSS and the Customer Order Status Notification feed must be enabled; the feed is disabled by default.
