In the wake of what happened with Huntarr today, what are some good solutions for vibecoders to check security?

For those that aren’t aware, Huntarr was a media search app that was vibecoded. A community member tried to flag some security concerns and got banned from the community. Well they dug deeper and found much worse security issues. Posted their findings online and it exploded.

So in the wake of that, what can we do to harden security on our vibecoded projects? Are there any good extensions or plugins or prompts to run or something?
