cvss-scoring SKILL.md skillA

cvss-scoring from hermeticormus/libresecops-claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add hermeticormus/libresecops-claude-code/cvss-scoring@git:20260930.71a2663

Pins git:20260930.71a2663 in mdr.lock. Pin the fingerprint instead.

Reference for CVSS v3.1 and v4.0 metrics, scoring guidance, and the difference between severity and remediation priority. Use when scoring a vulnerability, checking a vendor score, or explaining a CVSS vector.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# CVSS Scoring Methodology

> Reference knowledge base for the Common Vulnerability Scoring System (CVSS) v3.1 and v4.0, including metric definitions, scoring guidance, and practical application.

## Knowledge Base

### CVSS v3.1

CVSS v3.1 is the most widely used vulnerability scoring system. It produces a score from 0.0 to 10.0 across three metric groups: Base, Temporal, and Environmental.

#### Base Metrics

Base metrics represent the intrinsic characteristics of a vulnerability that are constant over time and across environments.

**Attack Vector (AV)** -- How the vulnerability is exploited:
| Value | Code | Description | Example |
|-------|------|-------------|---------|
| Network | N | Exploitable via network, no special access needed | Remote code execution via HTTP request |
| Adjacent | A | Requires adjacent network access (same LAN, Bluetooth, etc.) | ARP spoofing attack |
| Local | L | Requires local access (shell, physical keyboard, local app) | Privilege escalation from local user |
| Physical | P | Requires physical access to the device | USB-based attack, cold boot attack |

**Attack Complexity (AC)** -- Conditions beyond attacker control:

How to install

The exact contents, by fingerprint
mdr add hermeticormus/libresecops-claude-code/cvss-scoring@sha256:7430f87e64021a8f

The line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
