{"id":"GHSA-p6w8-q63m-72c8","summary":"Craft Commerce has Stored XSS in Tax Categories (Name & Description) Fields Leading to Potential Privilege Escalation","details":"## Summary\n\nA stored XSS vulnerability in Craft Commerce allows attackers to execute malicious JavaScript in an administrator’s browser. This occurs because the Tax 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 taxes\n- An active administrator elevated session\n\n### Steps to Reproduce\n1. Log in to the Admin Panel with the attacker account with the permissions mentioned above.\n2. Navigate to **Commerce** -\u003e **Store Management** -\u003e **Tax Categories** (`/admin/commerce/store-management/primary/taxcategories`).\n3. Create a new tax category.\n4. In the **Name** or **Description** field, enter the following payload:\n```html\n\u003cimg src=x onerror=\"alert(document.domain)\"\u003e\n```\n4. Click **Save** and you'll be redirected back to the previous page.\n5. Notice the alert proving JavaScript execution.\n\n### Privilege Escalation to Administrator:\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```\n\n3. In another browser, log in as an admin & go to the vulnerable page (tax 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### References:\n\nhttps://github.com/craftcms/commerce/commit/fa273330807807d05b564d37c88654cd772839ee","aliases":["CVE-2026-25488"],"modified":"2026-02-03T21:51:15.391273Z","published":"2026-02-02T22:51:51Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-02-02T22:51:51Z","nvd_published_at":"2026-02-03T19:16:26Z","cwe_ids":["CWE-79"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/craftcms/commerce/security/advisories/GHSA-p6w8-q63m-72c8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25488"},{"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/commerce","ecosystem":"Packagist","purl":"pkg:composer/craftcms/commerce"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0-RC1"},{"fixed":"5.5.2"}]}],"versions":["5.0.0","5.0.1","5.0.10","5.0.10.1","5.0.11","5.0.11.1","5.0.12","5.0.12.1","5.0.12.2","5.0.13","5.0.14","5.0.15","5.0.16","5.0.16.1","5.0.16.2","5.0.17","5.0.18","5.0.19","5.0.2","5.0.3","5.0.4","5.0.5","5.0.6","5.0.7","5.0.8","5.0.9","5.1.0","5.1.0-beta.1","5.1.0-beta.2","5.1.0-beta.3","5.1.0.1","5.1.1","5.1.2","5.1.3","5.1.4","5.2.0","5.2.1","5.2.10","5.2.11","5.2.12","5.2.12.1","5.2.2","5.2.2.1","5.2.3","5.2.4","5.2.5","5.2.6","5.2.7","5.2.8","5.2.9","5.2.9.1","5.3.0","5.3.0.1","5.3.0.2","5.3.1","5.3.10","5.3.11","5.3.12","5.3.13","5.3.2","5.3.2.1","5.3.2.2","5.3.3","5.3.4","5.3.5","5.3.6","5.3.7","5.3.8","5.3.9","5.4.0","5.4.1","5.4.1.1","5.4.10","5.4.2","5.4.3","5.4.4","5.4.5","5.4.5.1","5.4.6","5.4.7","5.4.7.1","5.4.8","5.4.9","5.5.0","5.5.0.1","5.5.1"],"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-p6w8-q63m-72c8/GHSA-p6w8-q63m-72c8.json"}},{"package":{"name":"craftcms/commerce","ecosystem":"Packagist","purl":"pkg:composer/craftcms/commerce"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0-RC1"},{"fixed":"4.10.1"}]}],"versions":["4.0.0","4.0.0-RC1","4.0.1","4.0.2","4.0.3","4.0.4","4.1.0","4.1.1","4.1.2","4.1.3","4.10.0","4.2.0","4.2.1","4.2.10","4.2.11","4.2.2","4.2.3","4.2.4","4.2.5","4.2.5.1","4.2.6","4.2.7","4.2.8","4.2.9","4.3.0","4.3.1","4.3.2","4.3.3","4.4.0","4.4.1","4.4.1.1","4.5.0","4.5.1","4.5.1.1","4.5.2","4.5.3","4.5.4","4.6.0","4.6.1","4.6.10","4.6.11","4.6.12","4.6.13","4.6.14","4.6.2","4.6.3.1","4.6.4","4.6.5","4.6.6","4.6.7","4.6.8","4.6.9","4.7.0","4.7.1","4.7.2","4.7.3","4.8.0","4.8.0.1","4.8.1","4.8.1.1","4.8.1.2","4.8.2","4.8.3","4.8.4","4.9.0","4.9.1","4.9.2","4.9.3","4.9.4"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-p6w8-q63m-72c8/GHSA-p6w8-q63m-72c8.json","last_known_affected_version_range":"\u003c= 4.10.0"}}],"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:L/SI:H/SA:N"}]}
