analyze-cve

analyze-cve is a skill for Claude Code from ShulkwiSEC/bb-huge. It costs 0 tokens per session (3,999 once invoked), scanned A, original, MIT.

A method for checking whether a known software vulnerability, called a CVE, can actually be reached through an application’s code. It follows data from user input to the vulnerable function and creates test requests for Burp Suite, a web-security testing tool.

In plain words
What is it for?
Tracing vulnerable code in Python, Node.js, Java, Go, Ruby, PHP, and other projects, assessing exploitability, and producing HTTP proof-of-concept requests.
Why use it?
It separates theoretical dependency vulnerabilities from issues the application can really be exploited through.

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

analyze-cve 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 8d 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.

CVE Vulnerability Analysis Workflow

Purpose

This workflow provides a structured methodology for analyzing whether a CVE affecting a project dependency poses a real security risk. It:

  • Traces vulnerable code paths in your application
  • Analyzes dataflow from user input to vulnerable functions
  • Creates proof-of-concept HTTP requests for Burp Suite validation

Language/Framework Agnostic: Works with Python, Node.js, Java, Go, Ruby, PHP, and more.

Important Assumptions

Trust User-Provided Information

  • The user has already verified the CVE and version through SCA tools (Snyk, Dependabot, GitHub Security, etc.)
  • Trust the dependency name, version, and CVE information provided - do not require verification
  • Do not fail if dependency files are missing or incomplete - focus on code analysis
  • Do not stop if packages aren't installed locally - many projects use private artifactories or complex build processes
  • Your job is to analyze CODE USAGE, not verify dependency versions

What This Means

  • If the user says "analyze CVE-X in package Y version Z", proceed with the analysis
  • Look for usage of the vulnerable code in the application
  • If you can't find dependency files, document this but continue the analysis
  • If the package isn't locally installed, work with the CVE description to understand what to look for

CHAIN COMMITMENTS — DECLARE BEFORE STARTING

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.

analyze-cve is a skill published in the GitHub repository ShulkwiSEC/bb-huge (22 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,999 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
