When applying for visa or ESTA to the US, if I have two (non-US) passports, what happens if I don't mention the second one?

You are legally required to disclose all passports on your ESTA form
Unless your second passport is from a country that the US really doesn't like, it's unlikely it would make any difference to your application
Lying on the ESTA form is not a great idea. If caught it may very well result in you being kicked out and being banned from the US for a non-trivial amount of time.
The US is unlikely to share your second passport info with anyone else. They have no reason to do so.
I don't think that anyone can assess the "probability" of the US detecting the omission of the second passport. Unless your second passport is already in a US federal data base, the chances are probably small, but they are not zero either. Why take the risk?
