This makes it possible for unauthenticated attackers to write a .php file to a web-served, PHP-executing location and, by supplying their own Google Drive file and OAuth token as the content source, execute arbitrary code on the server. The required save-design nonce is handed to anonymous callers by the nbd_check_use_logged_in endpoint, so it presents no barrier.","state":0,"publishedAt":"2026-10-14T01:27:13.964+00:00","modifiedAt":"2026-10-14T17:55:31.47+00:00","affected":[{"ecosystem":"Vendor product","name":"Printcart Store – Web to Print Product Designer for WooCommerce","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"printcart\",\n                    \"product\": \"Printcart Store – Web to Print Product Designer for WooCommerce\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"2.9.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/788461ba-2cf2-49d2-bbaa-a02de15f33ae?source=cve","https://plugins.trac.wordpress.org/changeset?reponame=&new=3716244%40printcart-integration%2Ftags%2F2.9.2&old=3715643%40printcart-integration%2Ftags%2F2.9.1","https://plugins.trac.wordpress.org/changeset/3716244/printcart-integration/trunk/includes/class.nbdesigner.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93388","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93388","identifiers":["CVE-2026-93388"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
