How to Fix GHSA-7jfh-2xc9-ccv7

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

public fixed: 0.1.4 
npm install public@0.1.4
public fixed: Latest secure release 
npm install public@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 public

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-7jfh-2xc9-ccv7, inspect your project dependencies using npm:

npm ls public

Analyze the terminal output to locate any version of Public in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.4), your application is affected.

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