### 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 serve the application: git clone https://github.com/NeoRazorX/facturascripts cd facturascripts php -S localhost:8000 Step 2 — Send the following unauthenticated GET request: GET /?phpinfo=TRUE HTTP/1.1 Host: localhost:8000 Step 3 — Observe full phpinfo() output returned (20+ pages) containing: - Complete PHP configuration - All server environment variables - Filesystem paths - Loaded extensions and versions - HTTP request headers No credentials, cookies, or prior interaction required. Tested on: PHP 8.1.34, macOS, fresh clone with no configuration applied. Proof of concept screenshot/PDF available. ### Impact Vulnerability type: Unauthenticated Information Disclosure (CWE-200) Any unauthenticated remote attacker who can reach a freshly deployed FacturaScripts instance before installation is completed can retrieve the full PHP environment. On production deployments this includes: - Database credentials (DB_PASSWORD, DB_USER) if set as environment variables - Application secrets (APP_KEY, JWT secrets) if set as environment variables - Cloud provider credentials (AWS_SECRET_ACCESS_KEY, etc.) if present - Full server filesystem paths enabling targeted path traversal attempts - Exact PHP version and loaded extensions enabling version-specific attacks - All HTTP headers revealing internal infrastructure details - Database connection configuration (mysqli default socket, PDO drivers) - Exact PHP version enabling version-specific CVE targeting (PHP 8.1.34) Fresh deployments are commonly left unconfigured for extended periods on shared hosting and cloud environments, making this window reliably exploitable in real-world scenarios. Fix: Remove lines 115-118 from Core/Controller/Installer.php: if ('TRUE' === $this->request->query('phpinfo', '')) { phpinfo(); return; }

AI coding agents often install or upgrade packages automatically in composer. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
