What is CVSS?

Also known as: Common Vulnerability Scoring System

Definition

CVSS is a standard maintained by FIRST for rating the technical severity of a vulnerability on a scale from 0 to 10.

Why it matters

The base score reflects properties such as attack vector, complexity, privileges needed and impact. It does not reflect whether the flaw is being exploited or how important the affected system is to you, so use it with KEV, EPSS and asset context.
