    CVE-2026-75920

    phpMyFAQ before v4.1.6 writes content backup ZIP archives to the web-accessible document root at content.zip, exposing sensitive files including database credentials. Unauthenticated attackers can race concurrent requests to download the temporary ZIP file before deletion, or exploit XSS in admin contexts to trigger authenticated backups and retrieve the archive.
