vuln-kb SKILL.md skillB
vuln-kb from dreadnode/capabilities is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dreadnode/capabilities/vuln-kb@git:20260529.8f6ea0ePins git:20260529.8f6ea0e in mdr.lock. Pin the fingerprint instead.

Local vulnerability knowledge base with CWE references, attack playbooks by tech stack, and detection signatures. Use when you need vulnerability context for a specific CWE, attack strategies for a technology stack, detection signatures for static analysis, or mapping between static analysis signals and vulnerability classes.
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
# Vulnerability Knowledge Base
Quick-reference for vulnerability classes, CWE mappings, and detection patterns. For full checklists and analysis strategies, see reference files in this directory.
## Lookup Workflow
1. **Identify signal** -- what did you find? (static analysis match, HTTP traffic pattern, error message)
2. **Map to vuln class** -- use the Signal -> Vulnerability table below
3. **Get CWE details** -- find the matching CWE section for test strategy and detection signals
4. **Verify** -- use the test commands and grep patterns to confirm
**Checkpoint:** Before reporting, confirm you have: CWE ID, working PoC, and impact statement.
## Signal -> Vulnerability Mapping
| Signal Pattern | Potential Vulnerability | Priority |
|---|---|---|
| `dangerouslySetInnerHTML` | DOM XSS (React) | High |
| `innerHTML` assignment | DOM XSS (vanilla JS) | High |
| `addEventListener('message')` | postMessage XSS / cross-origin abuse | High |
| `location.href` / `window.location` assignment | Open redirect / javascript: XSS | Medium |
| Hardcoded JWT / API keys in JS | Credential exposure | Critical |
| API paths with numeric IDs | IDOR candidates | Medium |

How to install
mdr add dreadnode/capabilities/vuln-kb@sha256:2418b42ad870b6beThe line at the top of this page pins the label git:20260529.8f6ea0e, 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.
