How to Fix CVE-2024-36857

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

@janhq/core fixed: Latest secure release 
npm install @janhq/core@Latest secure release
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 @janhq/core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-36857, inspect your project dependencies using npm:

npm ls @janhq/core

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

Note: The npm ls @janhq/core 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-31: Path Traversal: 'dir\..\..\filename', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize 'dir\..\..\filename' (multiple internal backslash dot dot) sequences that can resolve to a location that is outside of that directory. In @janhq/core, 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.
