Craft Commerce is an ecommerce platform for Craft CMS. In versions 4.0.0 through 4.10.2 and 5.0.0 through 5.5.4, the PaymentsController::actionPay discloses some order data to unauthenticated users when an order number is provided and the email check fails during an anonymous payment. The JSON error response includes the serialized order object (order), which contains some sensitive fields such as customer email, shipping address, and billing address. The frontend payment flow's actionPay() retrieves orders by number before authorization is fully enforcedLoad order by number. This issue has been fixed in versions 4.11.0 and 5.6.0.

Craft Commerce is an ecommerce platform for Craft CMS. In versions 4.0.0 through 4.10.2 and 5.0.0 through 5.5.4, there is an SQL injection vulnerability in the Commerce TotalRevenue widget which allows any authenticated control panel user to achieve remote code execution through a four-step exploitation chain. The attack exploits unsanitized widget settings interpolated into SQL expressions, combined with PDO's default multi-statement query support, to inject a maliciously serialized PHP object into the queue table. When the queue consumer processes the injected job, the unrestricted unserialize() call in yii2-queue instantiates a GuzzleHttp FileCookieJar gadget chain whose __destruct() method writes a PHP webshell to the server's webroot. The complete chain requires only three HTTP requests, no administrative privileges, and results in arbitrary command execution as the PHP process user, with queue processing triggered via an unauthenticated endpoint. This issue has been fixed in versions 4.10.3 and 5.5.5.

Craft Commerce is an ecommerce platform for Craft CMS. In versions 5.0.0 through 5.5.4, an SQL injection vulnerability exists where the ProductQuery::hasVariant and VariantQuery::hasProduct properties bypass the input sanitization blocklist added to ElementIndexesController in a prior security fix (GHSA-2453-mppf-46cj). The blocklist only strips top-level Yii2 Query properties such as where and orderBy, but hasVariant and hasProduct pass through untouched and internally call Craft::configure() on a subquery without sanitization, re-introducing SQL injection. Any authenticated control panel user can exploit this via boolean-based blind SQL injection to extract arbitrary database contents, including security keys that enable forging admin sessions for privilege escalation. This issue has been fixed in version 5.6.0.

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.11.0 and 5.6.0, An Insecure Direct Object Reference (IDOR) vulnerability exists in Craft Commerce’s cart functionality that allows users to hijack any shopping cart by knowing or guessing its 32-character number. The CartController accepts a user-supplied number parameter to load and modify shopping carts. No ownership validation is performed - the code only checks if the order exists and is incomplete, not whether the requester has authorization to access it. This vulnerability enables the takeover of shopping sessions and potential exposure of PII. This vulnerability is fixed in 4.11.0 and 5.6.0.

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 5.5.3, A stored XSS vulnerability exists in the Commerce Settings - Inventory Locations page. The Name field is rendered without proper HTML escaping, allowing an attacker to execute arbitrary JavaScript. This XSS triggers when an administrator (or user with product editing permissions) creates or edits a variant product. This vulnerability is fixed in 5.5.3.

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 5.5.3, Stored XSS vulnerabilities exist in the Commerce Inventory page. The Product Title, Variant Title, and Variant SKU fields are rendered without proper HTML escaping, allowing an attacker to execute arbitrary JavaScript when any user (including administrators) views the inventory management page. This vulnerability is fixed in 5.5.3.

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.

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 5.5.3, Craft Commerce is vulnerable to SQL Injection in the inventory levels table data endpoint. The sort[0][direction] and sort[0][sortField] parameters are concatenated directly into an addOrderBy() clause without any validation or sanitization. An authenticated attacker with access to the Commerce Inventory section can inject arbitrary SQL queries, potentially leading to a full database compromise. This vulnerability is fixed in 5.5.3.

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.10.2 and 5.5.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Craft Commerce Order details. Malicious JavaScript can be injected via the Shipping Method Name, Order Reference, or Site Name. When a user opens the order details slideout via a double-click on the order index page, the injected payload executes. This vulnerability is fixed in 4.10.2 and 5.5.3.

Craft Commerce is an ecommerce platform for Craft CMS. In versions from 4.0.0-RC1 to 4.10.0 and from 5.0.0 to 5.5.1, a stored XSS vulnerability in Craft Commerce allows attackers to execute malicious JavaScript in an administrator’s browser. This occurs because the 'Address Line 1' field in Inventory Locations is not properly sanitized before being displayed in the admin panel. This issue has been patched in versions 4.10.1 and 5.5.2.
