PhpSpreadsheet vulnerable to SSRF when reading and displaying a processed HTML document in the browser

CVE-2025-54370GHSA-rx7m-68vc-ppxh

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (phpoffice/phpspreadsheet 5.0.0, 3.10.0, 2.4.0, 2.1.12, 1.30.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2025-54370

Advisory: PhpSpreadsheet vulnerable to SSRF when reading and displaying a processed HTML document in the browser
IDs: CVE-2025-54370, GHSA-rx7m-68vc-ppxh
Record: https://patchnext.com/advisories/cve-2025-54370 (revision 1, source checked 26 Oct 2026, 14:34 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: phpoffice/phpspreadsheet 5.0.0, 3.10.0, 2.4.0, 2.1.12, 1.30.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist phpoffice/phpspreadsheet: affected < 1.30.0; >= 2.0.0, < 2.1.12; >= 2.2.0, < 2.4.0; >= 3.0.0, < 3.10.0; >= 4.0.0, < 5.0.0; fixed in 2.4.0, 2.1.12, 1.30.0, 3.10.0, 5.0.0

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

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on phpoffice/phpspreadsheet.
- 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
