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."}], "title": "Printcart Store - Web to Print Product Designer for WooCommerce (PCDesigner) <= 2.9.1 - Unauthenticated Arbitrary File Upload to Remote Code Execution via nbdesigner_copy_image_from_url", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/788461ba-2cf2-49d2-bbaa-a02de15f33ae?source=cve"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&new=3716244%40printcart-integration%2Ftags%2F2.9.2&old=3715643%40printcart-integration%2Ftags%2F2.9.1"}, {"url": "https://plugins.trac.wordpress.org/changeset/3716244/printcart-integration/trunk/includes/class.nbdesigner.php"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-434 Unrestricted Upload of File with Dangerous Type", "cweId": "CWE-434", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"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"}}], "credits": [{"lang": "en", "type": "finder", "value": "Osman Hussein"}], "timeline": [{"time": "2026-10-13T13:14:38.000Z", "lang": "en", "value": "Disclosed"}]}}}
