Unauthenticated environment disclosure via phpinfo query

Published May 27, 2026 · Updated May 27, 2026

Information disclosure in the Installer controller in FacturaScripts allows remote attackers to read PHP runtime details without authentication. Installer.php compares the phpinfo query value with the literal TRUE and calls phpinfo(), returning configuration and environment data. The route is reachable only before database configuration is completed; exposed output includes filesystem paths, extensions, and secrets stored in environment variables.
