The vulnerability exists because of a CSV escape-character mismatch between the exporter and the importer: class-csvwriter.php writes cells with fputcsv() using PHP's default backslash (\\) escape character, while class-csvreader.php parses the same file with fgetcsv() using a double-quote (\") as the escape character. As a result, a crafted value stored in a Subscriber's Biographical Info field — containing a backslash-quote sequence followed by a newline — is written as a single quoted CSV field but parsed back as two separate rows on import. The injected second row is then processed by hf_create_customer() as a new user record whose user_login, user_pass, user_email, and role are entirely attacker-controlled, allowing the creation of an arbitrary Administrator account. This makes it possible for authenticated attackers with Subscriber-level access and above to escalate their privileges to Administrator.","severity":{"version":"3.1","score":8.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00347,"percentile":0.28625,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-116"],"published":"2026-10-30T04:32:43Z","modified":"2026-10-30T17:17:12Z","products":[{"vendor":"webtoffee","product":"export and import users and customers"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4d358e43-f193-42fd-b49a-1b2a943183f2?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/modules/user/import/import.php#L490"},{"url":"https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/classes/class-csvreader.php#L197"},{"url":"https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/classes/class-csvwriter.php#L154"},{"url":"https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/modules/user/export/export.php#L560"},{"url":"https://plugins.trac.wordpress.org/changeset/3741112/users-customers-import-export-for-wp-woocommerce"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104368"},{"url":"https://github.com/advisories/GHSA-9339-975x-grvq"}],"sources":{"cve":[{"id":"CVE-2026-104368","title":"Export and Import Users and Customers \u003c= 2.7.5 - Authenticated (Subscriber+) Privilege Escalation via CSV Escape-Character Mismatch in Export/Import Round Trip via Biographical Info Field","description":"The Export and Import Users and Customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.7.5 via the plugin's own export and re-import workflow.
