Zero-Day Exploit
A zero-day exploit is a cyberattack that takes advantage of a previously unknown software vulnerability that the vendor has not yet patched. This means there are "zero days" for the developer to create a fix before the attack occurs.
TECHNICAL DEFINITION
A zero-day exploit leverages a critical, unpatched software vulnerability (zero-day vulnerability) unknown to the vendor and security community, enabling attackers to compromise systems before a patch is available and often bypass traditional security defenses due to its novelty.
BACKGROUND
A zero-day is a vulnerability or security hole in a computer system unknown to its developers or anyone capable of mitigating it. Until the vulnerability is remedied, threat actors can exploit it in a zero-day exploit, or zero-day attack.

USAGE NOTE
Zero-day exploits are highly prized by attackers and nation-state actors due to their effectiveness and stealth, making them a significant threat.
