{"id":"CVE-2026-104368","state":"PUBLISHED","title":"Export and Import Users and Customers <= 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. 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.","publishedAt":"2026-10-30T04:32:43.217Z","updatedAt":"2026-10-30T17:02:26.821Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["webtoffee Export and Import Users and Customers"],"affected":[{"vendor":"webtoffee","product":"Export and Import Users and Customers","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.7.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4d358e43-f193-42fd-b49a-1b2a943183f2?source=cve","https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/modules/user/import/import.php#L490","https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/classes/class-csvreader.php#L197","https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/classes/class-csvwriter.php#L154","https://plugins.trac.wordpress.org/browser/users-customers-import-export-for-wp-woocommerce/tags/2.7.5/admin/modules/user/export/export.php#L560","https://plugins.trac.wordpress.org/changeset/3741112/users-customers-import-export-for-wp-woocommerce"],"weaknesses":["CWE-116"],"ingestedAt":"2026-10-30T17:08:06.673Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104368.json","commit":"8a581a9da6180c99fa3232113dad4f8398ccbcc4","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104368","state":"PUBLISHED","datePublished":"2026-10-30T04:32:43.217Z","dateUpdated":"2026-10-30T17:02:26.821Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-01T21:48:40.164Z"},"containers":{"cna":{"title":"Export and Import Users and Customers <= 2.7.5 - Authenticated (Subscriber+) Privilege Escalation via CSV Escape-Character Mismatch in Export/Import Round Trip via Biographical Info Field","descriptions":[{"lang":"en","value":"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.
