🛡️ Definition & Threat Standard

The Common Vulnerability Scoring System (CVSS) v3.1 / v4.0 is an open standard assessing software vulnerability severity. The Base Metric Group captures intrinsic exploit characteristics across Attack Vector (AV), Privileges Required (PR), and Impact metrics (C/I/A), yielding a composite score from 0.0 (None) to 10.0 (Critical).
