CVE-2023-6160Network attack vector

CSV disclosure and deletion via path traversal

Published Nov 22, 2023 · Updated Apr 8, 2026

Path traversal in LifterLMS 7.4.2 and earlier allows remote authenticated users to read and delete arbitrary CSV files on the server. The maybe_serve_export function fails to confine a requested export path to the intended directory before serving and removing the referenced CSV file. Administrator or LMS manager access is required, and the effect is limited to CSV files accessible to the web server process.
