Hi,

Thank you for trying ShiftLeft Scan. I noticed that the dependency scanner has highlighted a number of open source vulnerabilities for this repo.

While the reported issues is not a big deal for a presentation, it will be nice if you could triage it or include some notes in the readme about the findings so that people who are cloning this can upgrade the packages to fix the issue and send you a PR.

Thanks.
