> A zero-day (also known as 0-day) vulnerability is a computer-software vulnerability that is unknown to, or unaddressed by, those who should be interested in mitigating the vulnerability (including the vendor of the target software)[0]

Why should a publicly known unpatched vulnerability be a lesser concern than something that you don't know exists?
