How to Fix CVE-2023-50475

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

bsock fixed: Latest secure release 
npm install bsock@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 bsock

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-50475, inspect your project dependencies using npm:

npm ls bsock

Analyze the terminal output to locate any version of Bsock 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 bsock command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
