Command injection in total.js

CVE-2020-28494GHSA-4449-hg37-77v8

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (total.js 3.4.7), 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.

Source description

As published by the source; long descriptions are shortened.

There is a command injection vulnerability that affects the package total.js before version 3.4.7. The issue occurs in the image.pipe and image.stream functions. The type parameter is used to build the command that is then executed using childprocess.spawn. The issue occurs because childprocess.spawn is called with the option shell set to true and because the type parameter is not properly sanitized.

# Patch Next advisory brief: CVE-2020-28494

Advisory: Command injection in total.js
IDs: CVE-2020-28494, GHSA-4449-hg37-77v8
Record: https://patchnext.com/advisories/cve-2020-28494 (revision 2, source checked 26 Oct 2026, 12:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: total.js 3.4.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm total.js: affected < 3.4.7; fixed in 3.4.7

## Suggested inspection (read-only)
- `npm ls total.js --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## 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 total.js.
- 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.
