• CVE-2017-16222: 1.68% estimated exploitation activity in the next 30 days; percentile 76.92 (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.

Affected versions of elding resolve relative file paths, resulting in a directory traversal vulnerability. A malicious actor can use this vulnerability to access files outside of the intended directory root, which may result in the disclosure of private files on the vulnerable system. This vulnerability only affects files that have file extensions - i.e. /etc/passwd will be treated as a directory, and a read attempt on /etc/passwd/index.js will be made and subsequently fail. Example request: Recommendation No patch is available for this vulnerability. It is recommended that the package is only used for local development, and if the functionality is needed for production, a different package is used instead.

# Patch Next advisory brief: CVE-2017-16222

Advisory: Directory Traversal in elding
IDs: CVE-2017-16222, GHSA-rp28-29ch-gh92
Record: https://patchnext.com/advisories/cve-2017-16222 (revision 2, source checked 26 Oct 2026, 12:25 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
- npm elding: affected <= 1.0.0

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

## 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 elding.
- 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.
