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.","categories":["Unclassified"],"product":"Printcart Store – Web to Print Product Designer for WooCommerce","vendor":"printcart","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93388","source_modified_at":"2026-10-14T17:55:31.470Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Printcart Store – Web to Print Product Designer for WooCommerce","vendor":"printcart","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.9.1","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00854,"percentile":0.57905,"score_date":"2026-10-23"},"published_at":"2026-10-14T01:27:13.964Z","modified_at":"2026-10-14T17:55:31.470Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93388","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T17:55:31.470Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93388","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/788461ba-2cf2-49d2-bbaa-a02de15f33ae?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3716244%40printcart-integration%2Ftags%2F2.9.2&old=3715643%40printcart-integration%2Ftags%2F2.9.1"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3716244/printcart-integration/trunk/includes/class.nbdesigner.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-14T17:55:19.566462Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T17:55:31.470Z","content_hash":"d4a26d35410ea2884564683b4ff19216dd1e9bde228a0c67cc8f0f3296fe0409"}}
