npm install bb-builder@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 bb-builder

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-vm6v-w6q2-mrrq, inspect your project dependencies using npm:

npm ls bb-builder

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

Technical Details

Source Advisory Statement

All versions of `bb-builder` contained malicious code. The package ran an executable targeting Windows and uploaded information to a remote server. ## Recommendation Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
