# analyzing-sbom-for-supply-chain-vulnerabilities Parses CycloneDX and SPDX SBOM files, matches components against the NVD CVE database through the NVD 2.0 API and builds a dependency graph. Useful when you need to size up third-party library risk. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 444 installs · ★ 35034 - Author: mukul975 - License: Apache-2.0 · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md - Updated: 2026-08-31 - HTML: https://affpapa.org/en/nevibecode/skills/analyzing-sbom-for-supply-chain-vulnerabilities ## What it does The skill reads an SBOM in CycloneDX JSON (v1.4+) or SPDX JSON (v2.3+), pulls out components with their PURL and CPE identifiers, and looks up known vulnerabilities in NVD through the 2.0 API. It then builds a directed dependency graph with networkx and scores risk: the highest CVSS across a component's CVEs, adjusted by how many packages depend on it. Levels are plain — CRITICAL from 9.0, HIGH from 7.0, MEDIUM from 4.0, everything else LOW. Transitive dependencies get their own pass. A flaw four levels deep is still a risk, it is just harder to fix. The graph shows how many components depend on a package, how close it sits to the entry point, and how many paths run through it. Grype cross-validation scans the same SBOM independently so you can compare findings. You need Python 3.9+ with requests, networkx and packaging, plus an NVD API key. Without a key the limit is 5 requests per 30 seconds; with one it is 50. On a large SBOM that gap shows up fast, so get the key up front. Syft helps if you still have to generate the SBOM. This is not for scanning live systems — the work happens on a file, not a running host. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-sbom-for-supply-chain-vulnerabilities -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/analyzing-sbom-for-supply-chain-vulnerabilities/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-sbom-for-supply-chain-vulnerabilities -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-sbom-for-supply-chain-vulnerabilities -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install mukul975/Anthropic-Cybersecurity-Skills analyzing-sbom-for-supply-chain-vulnerabilities ``` 2. **Manually: put the files in place** - File: `.github/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-sbom-for-supply-chain-vulnerabilities -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/mukul975/Anthropic-Cybersecurity-Skills --path skills/analyzing-sbom-for-supply-chain-vulnerabilities ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-sbom-for-supply-chain-vulnerabilities -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/analyzing-sbom-for-supply-chain-vulnerabilities/SKILL.md ## When to use it - parse a vendor SBOM and surface vulnerable components - map CycloneDX or SPDX packages to CVE records in NVD - build a dependency graph and trace transitive paths to a vulnerability - score component risk by how many packages depend on it - cross-check your findings against an independent grype scan ## Example prompts - analyze sbom-cyclonedx.json and list components with critical CVEs - build a dependency graph from this SPDX file and find transitive vulnerabilities - score the SBOM risk and compare it with grype results ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.
