How to Fix CVE-2024-42471

To remediate this vulnerability, upgrade all affected @actions/artifact dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@actions/artifact fixed: 2.1.2 
npm install @actions/artifact@2.1.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @actions/artifact

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-42471, inspect your project dependencies using npm:

npm ls @actions/artifact

Analyze the terminal output to locate any version of @actions/artifact in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.2), your application is affected.

Note: The npm ls @actions/artifact command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In @actions/artifact, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Versions of `actions/artifact` before 2.1.7 are vulnerable to arbitrary file write when using `downloadArtifactInternal`, `downloadArtifactPublic`, or `streamExtractExternal` for extracting a specifically crafted artifact that contains path traversal filenames. ### Patches Upgrade to version 2.1.7 or higher. ### References - https://snyk.io/research/zip-slip-vulnerability - https://github.com/actions/toolkit/pull/1724 ### CVE CVE-2024-42471 ### Credits Justin Taft from Google
