Zero-Day Exploit definition in Cybersecurity

A zero-day exploit is a cyber attack that occurs on the same day a weakness is discovered in software. At that point, it's exploited before a fix becomes available from its creator. Zero-day refers to the fact that the developers have "zero days" to fix the problem because it's already out in the open.
