How to Fix CVE-2018-14730

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

browserify-hmr fixed: 0.4.0 
npm install browserify-hmr@0.4.0
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 browserify-hmr

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-14730, inspect your project dependencies using npm:

npm ls browserify-hmr

Analyze the terminal output to locate any version of Browserify hmr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.4.0), your application is affected.

Note: The npm ls browserify-hmr 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Browserify hmr, 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

Versions of `browserify-hmr` prior to 0.4.0 are missing origin validation on the websocket server. This vulnerability allows a remote attacker to steal a developer's source code because the origin of requests to the websocket server that is used for Hot Module Replacement (HMR) are not validated. ## Recommendation Upgrade to version 0.4.0 or later.
