• CVE-2026-42878: 0.90% estimated exploitation activity in the next 30 days; percentile 59.80 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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', '')) {…

# Patch Next advisory brief: CVE-2026-42878

Advisory: FacturaScripts Vulnerable to Unauthenticated phpinfo() Disclosure via Installer Endpoint
IDs: CVE-2026-42878, GHSA-vrxf-vrc4-22p7
Record: https://patchnext.com/advisories/cve-2026-42878 (revision 1, source checked 26 Oct 2026, 14:48 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist facturascripts/facturascripts: affected >= 2026, <= 2026.1

## Suggested inspection (read-only)
- Packagist facturascripts/facturascripts: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on facturascripts/facturascripts.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-vrxf-vrc4-22p7 (GitHub-reviewed advisory GHSA-vrxf-vrc4-22p7 lists affected ranges: Packagist facturascripts/facturascripts >=2026 <=2026.1)
