A zero-day vulnerability is a security flaw in a system or device that is not yet known to the vendor or the public. It's called "zero-day" because there are zero days of protection against it. Hackers can exploit such vulnerabilities before the vendor has a chance to fix them, making them high-priority issues for security.
