{"id":"GHSA-w8gw-qm8p-j9j3","summary":"Craft Commerce has Stored XSS in Shipping Categories (Name & Description) Fields Leading to Potential Privilege Escalation","details":"## Summary\nA stored XSS vulnerability in Craft Commerce allows attackers to execute malicious JavaScript in an administrator’s browser. This occurs because the Shipping Categories (Name & Description) fields in the **Store Management** section are not properly sanitized before being displayed in the admin panel.\n\n---\n## Proof of Concept\n\n### Requirments\n- General permissions:\n\t- Access the control panel\n\t- Access Craft Commerce\n- Craft Commerce permissions:\n\t- Manage store settings\n\t- Manage shipping\n- An active administrator elevated session\n\n### Steps to Reproduce\n\n1. Log in to the Admin Panel with the attacker account with the permissions mentioned above.\n2. Navigate to **Commerce** -\u003e **Store Management** -\u003e **Shipping Categories** (`/admin/commerce/store-management/primary/shippingcategories`).\n3. Create a new shipping category.\n4. In the **Name** field, enter the following payload:\n```html\n\u003cimg src=x onerror=\"alert(document.domain)\"\u003e\n```\n4. Click **Save** & Go back to the previous page.\n5. Notice the alert proving JavaScript execution.\n\n\n### Privilege Escalation to Administrator:\n\n1. Do the same steps above, but replace the payload with a malicious one.\n2. The following payload elevates the attacker’s account to Admin if there’s already an elevated session, replace the `\u003cUserID\u003e` with your attacker id:\n```html\n\u003cimg src=x onerror=\"fetch('/admin/users/\u003cUserID\u003e/permissions',{method:'POST',body:`CRAFT_CSRF_TOKEN=${Craft.csrfTokenValue}&userId=\u003cUserID\u003e&admin=1&action=users/save-permissions`,headers:{'content-type':'application/x-www-form-urlencoded'}})\"\u003e\n```\n3. In another browser, log in as an admin & go to the vulnerable page (shipping categories page).\n4. Go back to your attacker account & notice you are now an admin.\n\nThe privilege escalation requires an elevated session. In a real-world scenario, an attacker can automate the process by forcing a logout if the victim’s session is stale; upon re-authentication, the stored XSS payload executes within a fresh elevated session to complete the attack.\n\nOr even easier (and smarter), an attacker (using the XSS) can create a fake 'Session Expired' login modal overlay. Since it’s on the trusted domain, administrators will likely enter their credentials, sending them directly to the attacker.\n\n### Resources:\n\nhttps://github.com/craftcms/commerce/commit/fa273330807807d05b564d37c88654cd772839ee","aliases":["CVE-2026-25485"],"modified":"2026-02-22T23:26:11.265129Z","published":"2026-02-02T22:45:03Z","database_specific":{"cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-02-02T22:45:03Z","nvd_published_at":"2026-02-03T19:16:26Z"},"references":[{"type":"WEB","url":"https://github.com/craftcms/commerce/security/advisories/GHSA-w8gw-qm8p-j9j3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25485"},{"type":"WEB","url":"https://github.com/craftcms/commerce/commit/fa273330807807d05b564d37c88654cd772839ee"},{"type":"PACKAGE","url":"https://github.com/craftcms/commerce"},{"type":"WEB","url":"https://github.com/craftcms/commerce/releases/tag/4.10.1"},{"type":"WEB","url":"https://github.com/craftcms/commerce/releases/tag/5.5.2"}],"affected":[{"package":{"name":"craftcms/composer","ecosystem":"Packagist","purl":"pkg:composer/craftcms/composer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0-RC1"},{"fixed":"5.5.2"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 5.5.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-w8gw-qm8p-j9j3/GHSA-w8gw-qm8p-j9j3.json"}},{"package":{"name":"craftcms/composer","ecosystem":"Packagist","purl":"pkg:composer/craftcms/composer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0-RC1"},{"fixed":"4.10.1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 4.10.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-w8gw-qm8p-j9j3/GHSA-w8gw-qm8p-j9j3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N"}]}
