Possible Unauthorized Data Exfiltration

[akiramicrobots]

When code is scanned why it is telling there is potential security thread ?
also, what is the need to stream the data to AWS S3 and Bitbucket ?

Possible Unauthorized Data Exfiltration
The script dynamically builds request URLs.

It might be sending sensitive data via opts (headers & payloads).

AWS S3, Bitbucket, and OpenAI API(this is required so we can ignore) were detected as potential destinations.

AWS S3 References (Possible Data Upload)
https://${options.bucket}.s3-accelerate.amazonaws.com

https://${options.bucket}.s3.${options.region}.amazonaws.com.cn

https://${options.bucket}.s3.amazonaws.com

https://s3-${options.region}.amazonaws.com/${options.bucket}

https://s3.amazonaws.com/${options.bucket}

📌 Risk:

These URLs suggest file uploads to AWS S3.

The script is dynamically setting the bucket and region, meaning it could be uploading to unknown AWS storage.

If your sensitive data is being sent here, this could be unauthorized exfiltration.

Thanks for raising this concern! Those AWS S3 and Bitbucket references are actually coming from the electron-updater library (v6.3.9) which we use for application updates.

While the security scanner is flagging these URLs, they're not actually used in our application. Our update system is configured to use GitHub exclusively, as you can see in the package.json:

"publish": [
{
"provider": "github",
"owner": "ibttf",
"repo": "interview-coder"
}
]

The S3 URLs like "${options.bucket}.s3.amazonaws.com" are template strings in electron-updater's unused code paths that support multiple update providers (S3, Bitbucket, etc.) but we don't use those providers.

If you examine our ProcessingHelper.ts file, you'll see the only external API calls we make are to OpenAI. We don't have any AWS credentials or S3 bucket configurations anywhere in our app.

You can verify this by monitoring the app's network traffic - you'll only see requests to OpenAI's API and GitHub (for checking updates).

I appreciate your vigilance about privacy and security!

Thanks for your clarification, Yes, we could see what you are mentioning here.

You are awesome, appreciate your work.

No worries at all!

The main goal with this project was to give the community an open-source alternative that's not locked behind a paywall. Many similar tools charge substantial subscription fees for essentially the same functionality, even though it's basically just GPT-4o mini API calls with some UI wrapped around it.

By making this open-source, we're hoping to democratize access to these interview preparation tools. Everyone should have access to quality resources regardless of their financial situation.

I'd love to see community contributions! If anyone wants to add features, optimize performance, or improve any aspect of the project, please feel free to submit PR requests. There's so much potential to expand this tool in interesting directions.
