This makes it possible for unauthenticated attackers to access any order's secret order_key and full billing and shipping PII — including first name, last name, email address, phone number, street address, postcode, city, region, and country — emitted inline as the klarna_payments_params JavaScript variable, enabling full store-wide order enumeration. Because WooCommerce order IDs are sequential integers and no order_key or authenticated session is required, every order in the store can be trivially enumerated with sequential GET requests to the order-pay endpoint."}],"title":"Klarna for WooCommerce <= 4.13.3 - Missing Authorization to Unauthenticated Sensitive Information Disclosure via 'order-pay' Endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c3abb96e-6ee2-4992-a122-9f661da9a4d6?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/klarna-payments-for-woocommerce/tags/4.13.3/classes/class-kp-assets.php#L185"},{"url":"https://plugins.trac.wordpress.org/browser/klarna-payments-for-woocommerce/tags/4.13.3/classes/class-kp-assets.php#L198"},{"url":"https://plugins.trac.wordpress.org/browser/klarna-payments-for-woocommerce/tags/4.13.3/classes/class-kp-assets.php#L204"},{"url":"https://plugins.trac.wordpress.org/browser/klarna-payments-for-woocommerce/tags/4.13.3/classes/class-kp-assets.php#L159"},{"url":"https://github.com/krokedil/klarna-payments-for-woocommerce/compare/4.13.3...f5362605a9901b7f9264cfa3b22fd782a7a3097b"},{"url":"https://plugins.trac.wordpress.org/changeset/3740915/klarna-payments-for-woocommerce/trunk/classes/class-kp-assets.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Kuba"}],"timeline":[{"time":"2026-10-14T15:00:10.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-15T15:50:36.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-110590","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-16T14:57:42.888860Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T15:09:39.428Z"}}]}}
