Command Injection in open

GHSA-28xh-wpgr-7fm8

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (open 6.0.0), 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.

Source description

As published by the source; long descriptions are shortened.

Versions of open before 6.0.0 are vulnerable to command injection when unsanitized user input is passed in. The package does come with the following warning in the readme: Recommendation open is now the deprecated opn package. Upgrading to the latest version is likely have unwanted effects since it now has a very different API but will prevent this vulnerability.

# Patch Next advisory brief: GHSA-28xh-wpgr-7fm8

Advisory: Command Injection in open
IDs: GHSA-28xh-wpgr-7fm8
Record: https://patchnext.com/advisories/ghsa-28xh-wpgr-7fm8 (revision 2, source checked 26 Oct 2026, 12:06 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: open 6.0.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm open: affected < 6.0.0; fixed in 6.0.0

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