Order disclosure via unchecked order identifier
Published Aug 21, 2026 · Updated Aug 21, 2026
Authorization bypass in affected J2Store releases allows remote attackers to read order details through a crafted order_id request. The checkout confirmation handler accepts a caller-controlled order_id and renders the referenced order without verifying that the requester owns or may view it. No authentication or user interaction is required; exposure is limited to the selected order's checkout confirmation content, including line items, prices, and totals.
