  "summary" : "Unauthenticated Spree Commerce users can view completed guest orders by Order ID",
  "details" : "### Unauthenticated users can view completed guest orders by Order ID (`GHSL-2026-029`)\n\nThe `OrdersController#show` action permits viewing completed guest orders by order number alone, without requiring the associated order token.\n\nOrder lookup without enforcing token requirement in [`OrdersController#show`](https://github.com/spree/spree/blob/1341623f2ae92685cdbe232885bf5808fc8f9ca8/storefront/app/controllers/spree/orders_controller.rb#L14):\n\n```ruby\n@order = complete_order_finder.new(number: params[:id], token: params[:token], store: current_store).execute.first\n```\n\nAuthorization bypass for guest orders in [`authorize_access`](https://github.com/spree/spree/blob/1341623f2ae92685cdbe232885bf5808fc8f9ca8/storefront/app/controllers/spree/orders_controller.rb#L51C1-L55C8):\n```ruby\ndef authorize_access\n  return true if @order.user_id.nil?\n\n  @order.user == try_spree_current_user\nend\n```\n\nIf the attacker is in possession of a leaked Order ID, they might look it up directly via this API.\nAlternatively, brute forcing all or parts of the possible Order IDs might be feasible for an attacker. (The Order IDs themselves are [securely generated](https://github.com/spree/spree/blob/a878eb4a782ce0445d218ea86fb12075b0e3d7cc/core/lib/spree/core/number_generator.rb#L45), but with relatively low entropy: by default an order ID has a length of 9 and a base of 10, that would require an attacker to perform 1 billion requests to gather all guest orders. (At an assumed constant rate of 100 requests per second it would take 115 days.)\n\n\n#### Proof of Concept\n\n1. As a guest create a complete order.\n2. Fetch the latest Order ID from the database (Table: `spree_orders`).\n3. In another clean browser access following URL: `<SPREE-HOST>/orders/<ORDER-ID>`. (Sample: `http://localhost:3000/orders/R496592563`)\n\n=> Full guest order details are disclosed including names, addresses and limited payment info.\n\n#### Impact\n\nThis issue may lead to disclosure of PII of guest users (including names, addresses and phone numbers).\n\n#### CWEs\n\n- CWE-639: Authorization Bypass Through User-Controlled Key\n\n### Credit\n\nThis issue was discovered with the [GitHub Security Lab Taskflow Agent](https://github.com/GitHubSecurityLab/seclab-taskflow-agent) and manually verified by GHSL team members [@p- (Peter Stöckli)](https://github.com/p-) and [@m-y-mo (Man Yue Mo)](https://github.com/m-y-mo).\n\n### Disclosure Policy\n\nThis report is subject to a 90-day disclosure deadline, as described in more detail in our [coordinated disclosure policy](https://securitylab.github.com/advisories#policy).",
