This makes it possible for authenticated attackers, with contributor-level access and above, to mint publicly accessible, session-free download links for arbitrary third-party orders, exposing customer names, billing and shipping addresses, email addresses, phone numbers, order and invoice numbers, line items, totals, payment details, and customer notes contained in those orders' invoices and packing slips. Exploitation requires the plugin's Document link access type setting to be configured to 'full'; with the default 'logged_in' value, generated URLs are signed with a per-session nonce rather than the order_key, making the shortcode path unexploitable for unauthorized access to third-party orders.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.14.0/includes/Endpoint.php#L111","https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.14.0/includes/Frontend.php#L271","https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.14.0/includes/Frontend.php#L284","https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.9.2/includes/Endpoint.php#L111","https://plugins.trac.wordpress.org/browser/woocommerce-pdf-invoices-packing-slips/tags/5.9.2/includes/Frontend.php#L271"],"products":[],"source":"nvd","synced_at":"2026-10-30T00:32:51.257498499+00:00"},"epss":{"cve":"CVE-2026-13116","score":0.00387,"percentile":0.32753,"date":"2026-10-29"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
