This is due to insufficient sanitization of the customer_note checkout field, which is inlined verbatim into invoice HTML, entity-decoded back into a live tag by simplehtmldom, reassembled into raw bytes by mPDF, and passed to unserialize() in _getObjAttr without validation. This makes it possible for unauthenticated attackers to execute code on the server. An unauthenticated attacker can trigger the vulnerable code path on a default install by placing an anonymous WooCommerce checkout via the public Store API (POST /wc/store/v1/checkout) using a Direct Bank Transfer or cheque payment method, which automatically transitions the order to 'on-hold' status and fires the plugin's invoice-generation hook."}],"affected":[{"source":"security@wordfence.com","affectedData":[{"vendor":"addonsorg","product":"PDF Invoice for WooCommerce + Drag and Drop Template Builder","defaultStatus":"unaffected","versions":[{"version":"0","lessThanOrEqual":"7.1.1","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}]},"weaknesses":[{"source":"security@wordfence.com","type":"Primary","description":[{"lang":"en","value":"CWE-502"}]}],"references":[{"url":"https://downloads.wordpress.org/plugin/pdf-for-woocommerce.7.2.0.zip","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/pdf-for-woocommerce/tags/7.1.1/frontend/index.php#L378","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/pdf-for-woocommerce/tags/7.1.1/libs/HtmlDocument.php#L300","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/pdf-for-woocommerce/tags/7.1.1/libs/HtmlNode.php#L1266","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/pdf-for-woocommerce/tags/7.1.1/vendor/mpdf/mpdf/src/Mpdf.php#L9105","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/pdf-for-woocommerce/tags/7.1.1/woocommerce/emails/index.php#L70","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/pdf-for-woocommerce/tags/7.1.1/woocommerce/shortcodes.php#L708","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1bc3529c-6161-4b89-8a35-c3a9b7b8c308?source=cve","source":"security@wordfence.com"}]}}]}
