How to Fix CVE-2024-43035

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

@fonoster/voice fixed: 0.6.1 
npm install @fonoster/voice@0.6.1
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 @fonoster/voice

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-43035, inspect your project dependencies using npm:

npm ls @fonoster/voice

Analyze the terminal output to locate any version of @fonoster/voice in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.6.1), your application is affected.

Note: The npm ls @fonoster/voice 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-24: Path Traversal: '../filedir', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "../" sequences that can resolve to a location that is outside of that directory. In @fonoster/voice, 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

Fonoster 0.5.5 before 0.6.1 allows ../ directory traversal to read arbitrary files via the /sounds/:file or /tts/:file VoiceServer endpoint. This occurs in serveFiles in mods/voice/src/utils.ts. NOTE: serveFiles exists in 0.5.5 but not in the next release, 0.6.1.
