This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify Peppol/EDI endpoint identifiers (`peppol_endpoint_id`, `peppol_endpoint_eas`) for any customer by specifying an arbitrary `order_id` parameter on systems using Peppol invoicing. This can affect order routing on the Peppol network and may result in payment disruptions and data leakage."}],"title":"PDF Invoices & Packing Slips for WooCommerce <= 5.6.0 - Missing Authorization to Authenticated (Subscriber+) Peppol Identifier Modification","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2e1922c6-e63b-47aa-97de-1e2382fa25d3?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.6.0/includes/Admin.php#L895"},{"url":"https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.6.0/includes/Admin.php#L72"},{"url":"https://wordpress.org/plugins/woocommerce-pdf-invoices-packing-slips/#developers"}],"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:L/UI:N/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Dmitrii Ignatyev"}],"timeline":[{"time":"2026-02-17T17:18:34.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-18T12:25:17.700241Z","id":"CVE-2026-1906","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-18T12:53:09.667Z"}}]}}
