CVSS v3.0CVSS v3.1text + json

Synopsis

cvss preset emits a canned CVSS vector that maps to a requested severity level — critical, high, medium, low, or none. The default version is 3.1; pass --version 3.0 for the v3.0 preset. Add --score to print the calculated score and severity alongside the vector. Useful as a known-good starting point for examples, tests, or templates.

How It Works

A severity argument selects a canned preset function keyed by version (e.g. CriticalV31 / CriticalV30); the result is a known-good vector, optionally printed with its score.

Usage

cvss preset [severity] [flags]

Flags

Flag	Default	Description
--format string	text	output format: text or json
--score	false	show score alongside vector string
--version string	3.1	CVSS version: 3.0 or 3.1
-h, --help	—	help for preset

Available severity levels

critical, high, medium, low, none

Examples

Critical v3.1

cvss preset critical
# Output:
# CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

High v3.0 with score

cvss preset --score --version 3.0 high
# Output:
# CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
# Score: 9.8 (Critical)

JSON

cvss preset --format json critical

Note the severity-vs-rating distinction

The requested severity (critical, high, …) names the preset bucket, while the computed severity rating may differ. In the --score example above, the high preset's v3.0 vector scores 9.8, whose rating rounds up to Critical — the bucket name and the numeric rating are not guaranteed to match exactly.

Underlying API

import "github.com/scagogogo/cvss-skills/pkg/cvss"

// v3.1 presets
cv := cvss.CriticalV31() // *Cvss3x
_ = cvss.HighV31()
_ = cvss.MediumV31()
_ = cvss.LowV31()
_ = cvss.NoneV31()

// v3.0 presets
_ = cvss.CriticalV30()
_ = cvss.HighV30()
_ = cvss.MediumV30()
_ = cvss.LowV30()
_ = cvss.NoneV30()

fmt.Println(cv.String())

// With --score:
calc := cvss.NewCalculator(cv)
score, _ := calc.Calculate()
fmt.Printf("Score: %.1f (%s)\n", score, cvss.GetSeverity(score))

Each severity level maps to a dedicated constructor: CriticalV31/HighV31/MediumV31/LowV31/NoneV31 for v3.1, and the *V30 counterparts for v3.0. All return *cvss.Cvss3x.
