## Why BRS-XSS?

**Context-Aware Detection** - Understands HTML, JavaScript, CSS, and attribute contexts for precise payload generation  
**Async Performance** - Scans 1000+ URLs in 12 minutes on 8 vCPU with intelligent rate limiting  
**CI/CD Ready** - SARIF output integrates directly with GitHub Security, GitLab, and other SAST platforms  
**WAF Evasion** - Advanced bypass techniques for Cloudflare, AWS WAF, ModSecurity, and 7+ popular WAFs  
**Enterprise Features** - Comprehensive reporting, payload deduplication, and production-safe defaults

## Quickstart (60 seconds)

### Install & Scan
```bash
pip install -U brs-xss
brs-xss scan https://target.tld -o out.sarif --fast
```

### Docker
```bash
docker run --rm -v $(pwd):/out ghcr.io/eptllc/brs-xss:latest scan https://target.tld -o /out/out.sarif
```

### GitHub Actions Integration
```yaml
- name: XSS Security Scan
  run: |
    pip install brs-xss
    brs-xss scan ${{ github.event.repository.html_url }} -o xss-results.sarif
    
- name: Upload SARIF
  uses: github/codeql-action/upload-sarif@v2
  with:
    sarif_file: xss-results.sarif
```

## Results & Reporting

### SARIF Integration
Perfect integration with GitHub Security tab, GitLab Security Dashboard, and SAST platforms:

Notes on SARIF 2.1.0 compliance:
- Includes driver.semanticVersion matching package version
- Each rule provides help text and helpUri
- run-level properties columnKind=utf16CodeUnits and defaultEncoding=utf-8 are set on save

```bash
# Scan and upload to GitHub Security
brs-xss scan https://app.example.com -o security.sarif
gh api repos/:owner/:repo/code-scanning/sarifs -f sarif=@security.sarif
```

### Interactive HTML Reports
Rich HTML reports with vulnerability details, payload explanations, and one-click replay:

```bash
brs-xss scan https://target.tld --output-html report.html
```

### JSON Schema Validation
Machine-readable results with full JSON Schema validation:

```json
{
  "scan_info": {
  "timestamp": "2025-09-08T09:03:08Z",
  "scanner": "BRS-XSS v1.0.5.1",
    "targets_scanned": 47,
    "vulnerabilities_found": 8,
    "false_positive_rate": "3.2%"
  },
  "vulnerabilities": [
    {
      "url": "https://app.example.com/search?q=test",
      "parameter": "q",
      "context": "html_attribute", 
      "payload": "\" onmouseover=\"alert(1)\"",
      "severity": "high",
      "confidence": 0.94,
      "cwe": "CWE-79",
      "sarif_rule_id": "XSS001"
    }
  ]
}
```
