{"id":"CVE-2026-1906","state":"PUBLISHED","title":"PDF Invoices & Packing Slips for WooCommerce <= 5.6.0 - Missing Authorization to Authenticated (Subscriber+) Peppol Identifier Modification","description":"The PDF Invoices & Packing Slips for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.6.0 via the `wpo_ips_edi_save_order_customer_peppol_identifiers` AJAX action due to missing capability checks and order ownership validation. 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.","publishedAt":"2026-02-18T05:29:17.309Z","updatedAt":"2026-04-08T16:44:19.177Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wpovernight PDF Invoices & Packing Slips for WooCommerce"],"affected":[{"vendor":"wpovernight","product":"PDF Invoices & Packing Slips for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.6.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/2e1922c6-e63b-47aa-97de-1e2382fa25d3?source=cve","https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.6.0/includes/Admin.php#L895","https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.6.0/includes/Admin.php#L72","https://wordpress.org/plugins/woocommerce-pdf-invoices-packing-slips/#developers"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1906.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1906","state":"PUBLISHED","datePublished":"2026-02-18T05:29:17.309Z","dateUpdated":"2026-04-08T16:44:19.177Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-04T15:19:56.700Z"},"containers":{"cna":{"title":"PDF Invoices & Packing Slips for WooCommerce <= 5.6.0 - Missing Authorization to Authenticated (Subscriber+) Peppol Identifier Modification","descriptions":[{"lang":"en","value":"The PDF Invoices & Packing Slips for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.6.0 via the `wpo_ips_edi_save_order_customer_peppol_identifiers` AJAX action due to missing capability checks and order ownership validation.
