# ClawSec Scanner
Comprehensive security scanner for agent platforms that automates vulnerability detection across multiple dimensions:
- **Dependency Scanning**: Analyzes npm and Python dependencies using `npm audit` and `pip-audit` with structured JSON output parsing
- **CVE Database Integration**: Queries OSV (primary), NVD 2.0, and GitHub Advisory Database for vulnerability enrichment
- **SAST Analysis**: Static code analysis using Semgrep (JavaScript/TypeScript) and Bandit (Python) to detect hardcoded secrets, command injection, path traversal, and unsafe deserialization
- **DAST Framework**: Basic dynamic analysis for skill hook security testing (input validation, timeout enforcement)
- **Unified Reporting**: Consolidated vulnerability reports with severity classification and remediation guidance
- **Continuous Monitoring**: OpenClaw hook integration for automated periodic scanning
## Features
### Multi-Engine Scanning
The scanner orchestrates four complementary scan types to provide comprehensive vulnerability coverage:
1. **Dependency Scanning**
- Executes `npm audit --json` and `pip-audit -f json` as subprocesses
- Parses structured output to extract CVE IDs, severity, affected versions
- Handles edge cases: missing package-lock.json, zero vulnerabilities, malformed JSON
2. **CVE Database Queries**
- **OSV API** (primary): Free, no authentication, broad ecosystem support (npm, PyPI, Go, Maven)
- **NVD 2.0** (optional): Requires API key to avoid 6-second rate limiting
- **GitHub Advisory Database** (optional): GraphQL API with OAuth token
- Normalizes all API responses to unified `Vulnerability` schema
3. **Static Analysis (SAST)**
- **Semgrep** for JavaScript/TypeScript: Detects security issues using `--config auto` or `--config p/security-audit`
- **Bandit** for Python: Leverages existing `pyproject.toml` configuration
- Identifies: hardcoded secrets (API keys, tokens), command injection (`eval`, `exec`), path traversal, unsafe deserialization
4. **Dynamic Analysis (DAST)**
- Test framework for skill hook security validation
- Verifies: malicious input handling, timeout enforcement, resource limits
- Note: Traditional web DAST tools (ZAP, Burp) do not apply to agent platforms - this provides agent-specific testing
### Unified Reporting
All scan types emit a consistent `ScanReport` JSON schema:
```typescript
{
scan_id: string; // UUID
timestamp: string; // ISO 8601
target: string; // Scanned path
vulnerabilities: Vulnerability[];
summary: {
critical: number;
high: number;
medium: number;
low: number;
info: number;
}
}
```
Each `Vulnerability` object includes:
- `id`: CVE-2023-12345 or GHSA-xxxx-yyyy-zzzz
- `source`: npm-audit | pip-audit | osv | nvd | github | sast | dast
- `severity`: critical | high | medium | low | info
- `package`: Package name (or 'N/A' for SAST/DAST)
- `version`: Affected version
- `fixed_version`: First version with fix (if available)
- `title`: Short description
- `description`: Full advisory text
- `references`: URLs for more info
- `discovered_at`: ISO 8601 timestamp
### OpenClaw Integration
Automated continuous monitoring via hook:
- Runs scanner on configurable interval (default: 86400s / 24 hours)
- Triggers on `agent:bootstrap` and `command:new` events
- Posts findings to `event.messages` array with severity summary
- Rate-limited by `CLAWSEC_SCANNER_INTERVAL` environment variable

## Usage
### On-Demand CLI Scanning
```bash
SCANNER_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-scanner"
# Scan all skills with JSON output
"$SCANNER_DIR/scripts/runner.sh" --target ./skills/ --output report.json --format json
# Scan specific directory with human-readable output
"$SCANNER_DIR/scripts/runner.sh" --target ./my-skill/ --format text
# Check available flags
"$SCANNER_DIR/scripts/runner.sh" --help
```
**CLI Flags:**
- `--target <path>`: Directory to scan (required)
- `--output <file>`: Write results to file (optional, defaults to stdout)
- `--format <json|text>`: Output format (default: json)
- `--check`: Verify all required binaries are installed
### OpenClaw Hook Setup (Continuous Monitoring)
Enable automated periodic scanning:
```bash
SCANNER_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-scanner"
node "$SCANNER_DIR/scripts/setup_scanner_hook.mjs"
```
This creates a hook that:
- Scans on `agent:bootstrap` and `command:new` events
- Respects `CLAWSEC_SCANNER_INTERVAL` rate limiting (default: 86400 seconds / 24 hours)
- Posts findings to conversation with severity summary
- Recommends remediation for high/critical vulnerabilities
Restart the OpenClaw gateway after enabling the hook, then run `/new` to trigger an immediate scan.
### Environment Variables
```bash
# Optional - NVD API key to avoid rate limiting (6-second delays without key)
export CLAWSEC_NVD_API_KEY="your-nvd-api-key"
# Optional - GitHub OAuth token for Advisory Database queries
export GITHUB_TOKEN="ghp_your_token_here"
# Optional - Scanner hook interval in seconds (default: 86400 / 24 hours)
export CLAWSEC_SCANNER_INTERVAL="86400"
# Optional - Allow unsigned advisory feed during development (from clawsec-suite)
export CLAWSEC_ALLOW_UNSIGNED_FEED="1"
```
## Architecture
### Modular Design
Each scan type is an independent module that can run standalone or as part of unified scan:
```
scripts/runner.sh # Orchestration layer
├── scan_dependencies.mjs # npm audit + pip-audit
├── query_cve_databases.mjs # OSV/NVD/GitHub API queries
├── sast_analyzer.mjs # Semgrep + Bandit static analysis
└── dast_runner.mjs # Dynamic security testing
lib/
├── report.mjs # Result aggregation and formatting
├── utils.mjs # Subprocess exec, JSON parsing, error handling
└── types.ts # TypeScript schema definitions
hooks/clawsec-scanner-hook/
├── HOOK.md # OpenClaw hook metadata
└── handler.ts # Periodic scan trigger
```
### Fail-Open Philosophy
The scanner prioritizes availability over strict failure propagation:
- Network failures → emit partial results, log warnings
- Missing tools → skip that scan type, continue with others
- Malformed JSON → parse what's valid, log errors
- API rate limits → implement exponential backoff, fallback to other sources
- Zero vulnerabilities → emit success report with empty array
**Critical failures** that exit immediately:
- Target path does not exist
- No scanning tools available (all bins missing)
- Concurrent scan detected (lockfile present)
### Subprocess Execution Pattern
All external tools run as subprocesses with structured JSON output:
```javascript
import { spawn } from 'node:child_process';
// Example: npm audit execution
const proc = spawn('npm', ['audit', '--json'], {
cwd: targetPath,
stdio: ['ignore', 'pipe', 'pipe']
});
// Handle non-zero exit codes gracefully
// npm audit exits 1 when vulnerabilities found (not an error!)
proc.on('close', code => {
if (code !== 0 && stderr.includes('ERR!')) {
// Actual error
reject(new Error(stderr));
} else {
// Vulnerabilities found or success
resolve(JSON.parse(stdout));
}
});
```
## Troubleshooting
### Common Issues
**"Missing package-lock.json" warning**
- `npm audit` requires lockfile to run
- Run `npm install` in target directory to generate
- Scanner continues with other scan types if npm audit fails
**"NVD API rate limit exceeded"**
- Set `CLAWSEC_NVD_API_KEY` environment variable
- Without API key: 6-second delays enforced between requests
- OSV API used as primary source (no rate limits)
**"pip-audit not found"**
- Install: `uv pip install pip-audit` or `pip install pip-audit`
- Verify: `which pip-audit`
- Add to PATH if installed in non-standard location
**"Semgrep binary missing"**
- Install: `pip install semgrep` OR `brew install semgrep`
- Requires Python 3.8+ runtime
- Alternative: use Docker image `returntocorp/semgrep`
**"Concurrent scan detected"**
- Lockfile exists: `/tmp/clawsec-scanner.lock`
- Wait for running scan to complete or manually remove lockfile
- Prevents overlapping scans that could produce inconsistent results
### Verification
Check scanner is working correctly:
```bash
# Verify required binaries
./scripts/runner.sh --check
# Run unit tests
node test/dependency_scanner.test.mjs
node test/cve_integration.test.mjs
node test/sast_engine.test.mjs
# Validate skill structure
python ../../utils/validate_skill.py .
# Scan test fixtures (should detect known vulnerabilities)
./scripts/runner.sh --target test/fixtures/ --format text
```
## Development
### Running Tests
```bash
# All tests (vanilla Node.js, no framework)
for test in test/*.test.mjs; do
node "$test" || exit 1
done
# Individual test suites
node test/dependency_scanner.test.mjs # Dependency scanning
node test/cve_integration.test.mjs # CVE database APIs
node test/sast_engine.test.mjs # Static analysis
```
### Linting
```bash
# JavaScript/TypeScript
npx eslint . --ext .ts,.tsx,.js,.jsx,.mjs --max-warnings 0
# Python (Bandit already configured in pyproject.toml)
ruff check .
bandit -r . -ll
# Shell scripts
shellcheck scripts/*.sh
```
### Adding Custom Semgrep Rules
Create custom rules in `.semgrep/rules/`:
```yaml
rules:
- id: custom-security-rule
pattern: dangerous_function($ARG)
message: Avoid dangerous_function - use safe_alternative instead
severity: WARNING
languages: [javascript, typescript]
```
Update `scripts/sast_analyzer.mjs` to include custom rules:
```javascript
const proc = spawn('semgrep', [
'scan',
'--config', 'auto',
'--config', '.semgrep/rules/', // Add custom rules
'--json',
targetPath
]);
```
## Integration with ClawSec Suite
The scanner works standalone or as part of the ClawSec ecosystem:
- **clawsec-suite**: Meta-skill that can install and manage clawsec-scanner
- **clawsec-feed**: Advisory feed for malicious skill detection (complementary)
- **openclaw-audit-watchdog**: Cron-based audit automation (similar pattern)
Install the full ClawSec suite:
```bash
npx clawhub@latest install clawsec-suite
# Then use clawsec-suite to discover and install clawsec-scanner
```
## Security Considerations
### Scanner Security
- No hardcoded secrets in scanner code
- API keys read from environment variables only (never logged or committed)
- Subprocess arguments use arrays to prevent shell injection
- All external tool output parsed with try/catch error handling
### Vulnerability Prioritization
**Critical/High severity findings** should be addressed immediately:
- Known exploits in dependencies (CVSS 9.0+)
- Hardcoded API keys or credentials in code
- Command injection vulnerabilities
- Path traversal without validation
**Medium/Low severity findings** can be addressed in normal sprint cycles:
- Outdated dependencies without known exploits
- Missing security headers
- Weak cryptography usage
**Info findings** are advisory only:
- Deprecated API usage
- Code quality issues flagged by linters
## Roadmap
### v0.1.0 (Current)
- [x] Dependency scanning (npm audit, pip-audit)
- [x] CVE database integration (OSV, NVD, GitHub Advisory)
- [x] SAST analysis (Semgrep, Bandit)

# ClawSec Scanner Hook
This hook performs comprehensive vulnerability scanning on installed skills and their dependencies on:
- `agent:bootstrap`
- `command:new`
When triggered, it runs all configured scanning engines (dependency scan, SAST, DAST, CVE database lookup) and posts findings as conversation messages. Scans are rate-limited by configurable interval to avoid performance impact.
## Scanning Capabilities
The hook orchestrates four independent scanning engines:
1. **Dependency Scanning**: Executes `npm audit` and `pip-audit` to detect known vulnerabilities in JavaScript and Python dependencies
2. **SAST (Static Analysis)**: Runs Semgrep (JS/TS) and Bandit (Python) to detect security issues like hardcoded secrets, command injection, and path traversal
3. **CVE Database Lookup**: Queries OSV API (primary), NVD 2.0 (optional), and GitHub Advisory Database (optional) for vulnerability enrichment
4. **DAST (Dynamic Analysis)**: Tests skill hook security including input validation, timeout enforcement, and resource limits
## Safety Contract
- The hook does not modify or delete skills.
- It only reports findings and provides remediation guidance.
- Scanning is non-blocking and runs on a configurable interval (default 24 hours).
- Failed scans (network errors, missing tools) produce warnings but do not block execution.
- Findings are deduplicated to avoid alert fatigue.
## Optional Environment Variables
### Core Configuration
- `CLAWSEC_SCANNER_INTERVAL`: Minimum interval between hook scans in seconds (default `86400` / 24 hours).
- `CLAWSEC_SCANNER_TARGET`: Override default scan target path (default: installed skills root).
- `CLAWSEC_SCANNER_STATE_FILE`: Override state file path for deduplication (default `~/.openclaw/clawsec-scanner-state.json`).
- `CLAWSEC_INSTALL_ROOT`: Override installed skills root directory.
### CVE Database Integration
- `CLAWSEC_NVD_API_KEY`: NVD API key for rate-limit-free access (without this, 6-second delays apply).
- `GITHUB_TOKEN`: GitHub OAuth token for GitHub Advisory Database queries (optional enhancement).
### Selective Scanning
- `CLAWSEC_SKIP_DEPENDENCY_SCAN`: Set to `1` to disable dependency scanning (npm audit, pip-audit).
- `CLAWSEC_SKIP_SAST`: Set to `1` to disable static analysis (Semgrep, Bandit).
- `CLAWSEC_SKIP_DAST`: Set to `1` to disable dynamic analysis (hook security tests).
- `CLAWSEC_SKIP_CVE_LOOKUP`: Set to `1` to disable CVE database enrichment.
### Advanced Options
- `CLAWSEC_SCANNER_TIMEOUT`: Maximum scan duration in seconds before timeout (default `300` / 5 minutes).
- `CLAWSEC_SCANNER_FORMAT`: Output format for findings (`json` or `text`, default `text`).
- `CLAWSEC_SCANNER_MIN_SEVERITY`: Minimum severity to report (`critical`, `high`, `medium`, `low`, `info`, default `medium`).
- `CLAWSEC_SCANNER_OUTPUT_FILE`: Optional path to write full scan report JSON (default: conversation only).
## Required Binaries
The hook requires the following binaries to be available on `PATH`:
- `node` (20+) - JavaScript runtime
- `npm` - For npm audit execution
- `python3` (3.10+) - Python runtime
- `pip-audit` - Python dependency scanner
- `semgrep` - JavaScript/TypeScript static analysis
- `bandit` - Python static analysis
- `jq` - JSON parsing and merging
- `curl` - API requests (fallback)
Missing binaries will be logged as warnings; available tools will still run.
