This makes it possible for authenticated attackers, with subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The base64-encoded file contents are embedded into the cached invoice HTML and served directly to the attacker via the plugin's own Print/Download invoice endpoints, which require only a valid nonce and access key."}],"title":"WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels <= 4.9.8 - Authenticated (Subscriber+) Arbitrary File Read via 'customer_note' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a46f270f-d9cb-4bc1-8e10-3fc6646e1d78?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/print-invoices-packing-slip-labels-for-woocommerce/tags/4.9.8/admin/modules/customizer/customizer.php#L1561"},{"url":"https://plugins.trac.wordpress.org/browser/print-invoices-packing-slip-labels-for-woocommerce/tags/4.9.8/admin/modules/customizer/customizer.php#L1607"},{"url":"https://plugins.trac.wordpress.org/browser/print-invoices-packing-slip-labels-for-woocommerce/tags/4.9.8/admin/modules/customizer/classes/class-customizer.php#L1453"},{"url":"https://plugins.trac.wordpress.org/browser/print-invoices-packing-slip-labels-for-woocommerce/tags/4.9.8/public/modules/invoice/invoice.php#L1934"},{"url":"https://plugins.trac.wordpress.org/changeset/3646629/print-invoices-packing-slip-labels-for-woocommerce"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","cweId":"CWE-22","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"daroo"}],"timeline":[{"time":"2026-08-06T08:41:52.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-22T10:37:45.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-18027","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-08-24T12:37:46.250703Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-24T13:01:19.729Z"}}]}}
