Official Description

FacturaScripts is an open source accounting and invoicing software. Prior to v2026, an unauthenticated information disclosure vulnerability in the Installer controller allows any remote attacker to trigger phpinfo() on a fresh FacturaScripts deployment by requesting /?phpinfo=TRUE, exposing full PHP configuration, server environment variables (including any database credentials, API keys, or application secrets set as env vars), filesystem paths, and loaded extensions without being authenticated. This vulnerability is fixed in v2026.
