{"id":"GHSA-3vxg-x5f8-f5qf","summary":"Craft Commerce has an unauthenticated information disclosure that can leak some customer order data on anonymous payments","details":"### Summary\n\n`PaymentsController::actionPay` discloses some order data to unauthenticated users when an order number is provided and the email check fails during an anonymous payment.\n\nThe JSON error response includes the serialized order object (`order`), which contains some sensitive fields such as customer email, shipping address, and billing address.\n\n### Details\n\nI manually audited frontend payment flows and found that `actionPay()` retrieves orders by number before authorization is fully enforced.\n\nCode path:\n\n1. Load order by `number`.\n2. Evaluate whether payment is authorized for completed orders (`number + matching email`).\n3. If unauthorized, return failure.\n4. Failure response still includes `cartArray($order)`, which serializes sensitive order data.\n\nWhy is this a vulnerability?\n\n- Authorization logic says the requester is not allowed to pay for a completed order without an email.\n- But the response still returns the same completed order’s contents.\n\n### Impact\n\nType: Information Disclosure / Broken Access Control\n\nWho is impacted:\n\n- Any Commerce deployment where completed order numbers can be obtained or leaked.","aliases":["CVE-2026-32270"],"modified":"2026-04-14T01:39:12.407891Z","published":"2026-04-14T01:01:17Z","database_specific":{"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-04-14T01:01:17Z","nvd_published_at":"2026-04-13T20:16:33Z","cwe_ids":["CWE-200","CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/craftcms/commerce/security/advisories/GHSA-3vxg-x5f8-f5qf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32270"},{"type":"WEB","url":"https://github.com/craftcms/commerce/commit/48a5d946419964e2af1ac64a8e1acc2a32ca0a08"},{"type":"PACKAGE","url":"https://github.com/craftcms/commerce"},{"type":"WEB","url":"https://github.com/craftcms/commerce/releases/tag/4.11.0"},{"type":"WEB","url":"https://github.com/craftcms/commerce/releases/tag/5.6.0"}],"affected":[{"package":{"name":"craftcms/commerce","ecosystem":"Packagist","purl":"pkg:composer/craftcms/commerce"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0"},{"fixed":"5.6.0"}]}],"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","5.5.2","5.5.3","5.5.4"],"database_specific":{"last_known_affected_version_range":"\u003c= 5.5.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-3vxg-x5f8-f5qf/GHSA-3vxg-x5f8-f5qf.json"}},{"package":{"name":"craftcms/commerce","ecosystem":"Packagist","purl":"pkg:composer/craftcms/commerce"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"4.11.0"}]}],"versions":["4.0.0","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","4.10.1","4.10.2","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":{"last_known_affected_version_range":"\u003c= 4.10.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-3vxg-x5f8-f5qf/GHSA-3vxg-x5f8-f5qf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U"}]}
