vulnerability.score.base

Scores can range from 0.0 to 10.0, with 10.0 being the most severe.

Base scores cover an assessment for exploitability metrics (attack vector, complexity, privileges, and user interaction), impact metrics (confidentiality, integrity, and availability), and scope. For example (https://www.first.org/cvss/specification-document)

type: float

example: 5.5

extended

vulnerability.score.environmental

Scores can range from 0.0 to 10.0, with 10.0 being the most severe.

Environmental scores cover an assessment for any modified Base metrics, confidentiality, integrity, and availability requirements. For example (https://www.first.org/cvss/specification-document)

type: float

example: 5.5

extended

vulnerability.score.temporal

Scores can range from 0.0 to 10.0, with 10.0 being the most severe.

Temporal scores cover an assessment for code maturity, remediation level, and confidence. For example (https://www.first.org/cvss/specification-document)

type: float

extended

vulnerability.score.version

The National Vulnerability Database (NVD) provides qualitative severity rankings of "Low", "Medium", and "High" for CVSS v2.0 base score ranges in addition to the severity ratings for CVSS v3.0 as they are defined in the CVSS v3.0 specification.

CVSS is owned and managed by FIRST.Org, Inc. (FIRST), a US-based non-profit organization, whose mission is to help computer security incident response teams across the world. For example (https://nvd.nist.gov/vuln-metrics/cvss)
