Description

Hi

Im running bandit against my python project (its a great tool, i love it!) but there are some things that could be improved

Im using subprocess.call, but with shell set to False, so im not vulnerable to command injection there. However, i have two errors in my build.

B404 - as im using subprocess
B607 - as, despite not being vulnerable to command injection, i need to be careful

Those recommendations are great, but in my opinion should be categorised as warnings rather than vulnerabilities. I have been reading and most of the people ignore those rules by default

Would be possible to have this amended?

Thanks

Research direction

Start by reviewing how Bandit categorizes the B404 and B607 findings and whether their severities are covered by tests. The issue is complete when those findings are classified as warnings rather than vulnerabilities without changing their detection behavior, with the relevant tests passing.
