tar-fs Vulnerable to Link Following and Path Traversal via Extracting a Crafted tar File

CVE-2024-12905GHSA-pq67-2wwv-3xjx

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (tar-fs 3.0.7, 2.1.2, 1.16.4), 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.

An Improper Link Resolution Before File Access ("Link Following") and Improper Limitation of a Pathname to a Restricted Directory ("Path Traversal"). This vulnerability occurs when extracting a maliciously crafted tar file, which can result in unauthorized file writes or overwrites outside the intended extraction directory. The issue is associated with index.js in the tar-fs package. This issue affects tar-fs: from 0.0.0 before 1.16.4, from 2.0.0 before 2.1.2, from 3.0.0 before 3.0.7. PoC

# Patch Next advisory brief: CVE-2024-12905

Advisory: tar-fs Vulnerable to Link Following and Path Traversal via Extracting a Crafted tar File
IDs: CVE-2024-12905, GHSA-pq67-2wwv-3xjx
Record: https://patchnext.com/advisories/cve-2024-12905 (revision 2, source checked 26 Oct 2026, 12:38 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: tar-fs 3.0.7, 2.1.2, 1.16.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm tar-fs: affected < 1.16.4; >= 2.0.0, < 2.1.2; >= 3.0.0, < 3.0.7; fixed in 2.1.2, 3.0.7, 1.16.4

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