This allows authenticated attackers with author-level permissions or above, if the administrator previously grants access in the plugin settings, to create a PHP file and execute code on the server. The author resolved this vulnerability by removing the ability for authors and editors to import files, please note that this means php file creation is still allowed for site administrators, use the plugin with caution.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94"],"references":["https://plugins.trac.wordpress.org/browser/wp-ultimate-csv-importer/tags/7.9.6/importExtensions/ImportHelpers.php#L205","https://plugins.trac.wordpress.org/changeset/2944635/wp-ultimate-csv-importer/trunk/wp-ultimate-csv-importer.php","https://www.wordfence.com/threat-intel/vulnerabilities/id/b4fe8b1f-da1c-4f94-9ab4-272766b488c3?source=cve","https://plugins.trac.wordpress.org/browser/wp-ultimate-csv-importer/tags/7.9.6/importExtensions/ImportHelpers.php#L205","https://plugins.trac.wordpress.org/changeset/2944635/wp-ultimate-csv-importer/trunk/wp-ultimate-csv-importer.php"],"products":["smackcoders:wp_ultimate_csv_importer"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-4141","score":0.01555,"percentile":0.75162,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
