OWASP Category Mapping

OWASP Category Mapping is a skill for Claude Code from allsmog/vuln-scout. It costs 56 tokens per session (1,237 once invoked), scanned A, original, MIT.

A reference for mapping security findings to the OWASP Top 10, a widely used list of common web application security risks, and to CWE weakness categories.

In plain words
What is it for?
Use it to classify findings such as access-control failures, injection, cryptographic failures, and security misconfiguration.
Why use it?
It keeps security reports consistent and uses familiar names when explaining what kind of weakness was found.

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

OWASP Category Mapping 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 12d 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.

OWASP Top 10 Reference

Purpose

Map VulnScout findings to official OWASP Top 10 category names, highlight what the plugin covers well, and keep reports aligned with widely recognized security terminology.

Reporting Rule

  • Use official OWASP Top 10 names in user-facing reports.
  • Treat the owasp-2025 directory name as a compatibility alias, not as proof of a future OWASP taxonomy.
  • Prefer CWE plus concrete vulnerability class when a finding does not fit cleanly into a single OWASP bucket.

Mapping Guidance

A01: Broken Access Control

Use for:

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.

OWASP Category Mapping is a skill published in the GitHub repository allsmog/vuln-scout (24 stars, last pushed 3mo ago), licensed MIT. It adds 56 tokens to every session and 1,237 once invoked, about $0.0003 per session on Opus 5. 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.
