Path Traversal in w-zip

CVE-2022-0401GHSA-fr6q-jv7j-35g3

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (w-zip 1.0.12), 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-2022-0401

Advisory: Path Traversal in w-zip
IDs: CVE-2022-0401, GHSA-fr6q-jv7j-35g3
Record: https://patchnext.com/advisories/cve-2022-0401 (revision 2, source checked 26 Oct 2026, 12:21 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: w-zip 1.0.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm w-zip: affected < 1.0.12; fixed in 1.0.12

## Suggested inspection (read-only)
- `npm ls w-zip --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 w-zip.
- 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.
