Associated Vulnerability

Title: FacturaScripts: Unauthenticated phpinfo() Disclosure via Installer Endpoint in FacturaScripts (CVE-2026-42878)
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.

Description

Detected FacturaScripts exposes a debug branch in the Installer controller that calls phpinfo() when the request carries the phpinfo=TRUE query parameter, and on an instance that has not finished installation, this endpoint was reachable without authentication.
