CVE-2026-25490

CVE-2026-25490: Craft Commerce has Stored XSS in Inventory Location Address Leading to Potential Privilege Escalation

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.

Root Cause Analysis

The vulnerability is a series of stored Cross-Site Scripting (XSS) issues within the Craft Commerce plugin's admin panel. The root cause is the failure to properly sanitize user-provided input before it is displayed on various administrative pages. The provided patch fa273330807807d05b564d37c88654cd772839ee reveals that multiple controller actions responsible for rendering tables of data (e.g., inventory locations, shipping categories, tax rates) were directly outputting values like names, descriptions, and addresses without HTML encoding. An attacker with permissions to edit these entities could insert malicious JavaScript into these fields. When a privileged user, such as an administrator, views the list pages for these items, the malicious script would execute in their browser's context. This could be used to steal session cookies, perform actions on behalf of the administrator, or as shown in the proof-of-concept, escalate the attacker's own privileges to that of an administrator. The fix applied across all affected files is to wrap the potentially unsafe data points with Html::encode(), which neutralizes the script content by converting HTML special characters into their entity equivalents, thus preventing the browser from executing them.

Vulnerable functions

craftcms\commerce\controllers\InventoryLocationsController::actionInventoryLocationsTableData

src/controllers/InventoryLocationsController.php

The function `actionInventoryLocationsTableData` is vulnerable to stored XSS because it uses the raw output of `$inventoryLocation->getAddressLine()` for the 'address' field. An attacker with permissions to manage inventory locations could save a malicious script in an address field, which would then be executed in the browser of an administrator viewing the inventory locations table.

craftcms\commerce\controllers\ShippingCategoriesController::actionIndex

src/controllers/ShippingCategoriesController.php

The `actionIndex` function in `ShippingCategoriesController` is vulnerable to stored XSS. The `name` and `description` of a shipping category were rendered without proper HTML encoding. This could allow an attacker with permissions to edit shipping categories to inject malicious scripts into these fields, which would execute in an administrator's browser when viewing the shipping categories list.

craftcms\commerce\controllers\ShippingMethodsController::actionIndex

src/controllers/ShippingMethodsController.php

The `actionIndex` function in `ShippingMethodsController` is vulnerable to stored XSS. The `name` of a shipping method was rendered without proper HTML encoding. An attacker with permissions to edit shipping methods could inject a malicious script into the name field, which would execute in an administrator's browser.

craftcms\commerce\controllers\ShippingZonesController::actionIndex

src/controllers/ShippingZonesController.php

The `actionIndex` function in `ShippingZonesController` is vulnerable to stored XSS. The `name` and `description` of a shipping zone were rendered without proper HTML encoding, allowing an attacker to inject malicious scripts.

craftcms\commerce\controllers\TaxCategoriesController::actionIndex

src/controllers/TaxCategoriesController.php

The `actionIndex` function in `TaxCategoriesController` is vulnerable to stored XSS. The `name` and `description` of a tax category were rendered without proper HTML encoding, allowing an attacker to inject malicious scripts.

craftcms\commerce\controllers\TaxRatesController::actionIndex

src/controllers/TaxRatesController.php

The `actionIndex` function in `TaxRatesController` is vulnerable to stored XSS. The `name` of a tax rate and the associated `taxZone->name` were rendered without proper HTML encoding, allowing an attacker to inject malicious scripts.

craftcms\commerce\controllers\TaxZonesController::actionIndex

src/controllers/TaxZonesController.php

The `actionIndex` function in `TaxZonesController` is vulnerable to stored XSS. The `name` and `description` of a tax zone were rendered without proper HTML encoding, allowing an attacker to inject malicious scripts.
