cve-triage

cve-triage is a skill for Claude Code, Codex from fb0sh/pentester. It costs 44 tokens per session (616 once invoked), scanned A, a copy of cve-triage, MIT.

A guide for looking up known security weaknesses, called CVEs, in discovered software versions and ranking them by severity and likelihood of exploitation.

In plain words
What is it for?
It is for querying the National Vulnerability Database, reviewing individual CVE records, comparing CVSS scores, and prioritizing follow-up verification after reconnaissance.
Why use it?
It turns service banners and version evidence into a shorter list of issues worth checking first, instead of treating every possible weakness equally.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cve-triage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CVE Triage

Turn version/banner evidence from recon into a prioritized, exploitability-aware list of CVEs worth verifying. Use this after fingerprinting a service, when a banner or Server: header reveals a product and version, or whenever the target exposes software with a known version.

The cve_lookup tool

VulnClaw ships a read-only cve_lookup tool backed by NVD:

  • Keyword searchcve_lookup(query="Apache httpd 2.4.49", limit=5) returns the top CVEs sorted by CVSS, highest first.
  • CVE-ID detailcve_lookup(query="CVE-2021-44228") returns the full record plus best-effort exploit / PoC repositories discovered on GitHub.

It performs no egress to the target and is safe during recon. Without an NVD_API_KEY it still works (lower rate limit); set one for heavier use.

Workflow

  1. Extract product + version from recon — service banners, Server headers, JS bundles, login footers, package manifests. A precise version string (OpenSSH 8.2p1, nginx 1.18.0) yields far better matches than a bare name.
  2. Query cve_lookup with "<product> <version>". Pull the detail record for any high/critical hit by re-querying its CVE-ID.
  3. Score & prioritize — see references/cve-triage-workflow.md. Rank by CVSS, then by exploit availability, then by exposure (is the vulnerable surface actually reachable on this target?).
  4. Confirm version applicability — match the target's version against the CVE's affected cpe range before claiming it. Banner ≠ proof of vulnerability.
  5. Record findings with the CVE-ID, CVSS, and the evidence that maps this target to it. Mark unconfirmed version-only matches as needs-manual-review, not verified.

Pitfalls

  • A keyword match is a hypothesis, not a finding — version ranges and backported patches mean a banner version can be patched in place.
  • GitHub "PoC" repos are unverified third-party code; treat as leads, never run blindly against a target.
  • Prefer the CVSS base score for triage, but let exploit availability and real exposure override raw score when prioritizing verification effort.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
