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.

GHSA-vrxf-vrc4-22p7 — FacturaScripts Vulnerable to Unauthenticated phpinfo() Disclosure via Installer Endpoint

Affected: Packagist: facturascripts/facturascripts

### Summary 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.

### Details The phpinfo() debug endpoint was intentionally added in commit 8c31c106 ("Added phpinfo option to the installer") on February 27, 2018, and has remained in the codebase for over 8 years across multiple major versions.

The feature appears to have been added as a convenience tool to help users diagnose PHP configuration during installation. However, it exposes sensitive server information to any unauthenticated attacker who knows the parameter.

Vulnerable code (Core/Controller/Installer.php ~line 115):

if ('TRUE' === $this->request->query('phpinfo', '')) { phpinfo(); return; }

This vulnerability is of the same class as CVE-2025-34081 (CONPROSYS HMI System unauthenticated phpinfo() exposure), which received a CVE assignment.

Introduced: commit 8c31c1060581ad6ad591c7689da3a8df8a29f486 (Feb 27 2018) Still present: v2026-39-g262e79208 (confirmed April 2026)

### PoC Prerequisites: Fresh FacturaScripts deployment where installation has not yet been completed (config.php does not contain db_name).

Step 1 — Clone and s…
