## Critical Findings
### SEC-001: SQL Injection in User Search
**CVSS Score:** 9.8 (Critical)
**Location:** `src/api/users.ts:47`
**Attack Vector:**
POST /api/users?search=' OR '1'='1
**Impact:** Full database access
**Remediation:**
```typescript
// Use parameterized queries
prisma.user.findMany({ where: { name: { contains: search } } })
CVSS Score: 9.1 (Critical)
Location: src/lib/stripe.ts:5
Issue: Production API key in source code
const stripe = new Stripe('sk_live_xxxxx'); // EXPOSED!
Remediation:
const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!);
CVSS Score: 8.6 (Critical)
Location: src/app/api/fetch/route.ts:12
Issue: User-controlled URL in fetch
const response = await fetch(req.query.url); // SSRF!
Remediation: Validate URL against allowlist
CVSS Score: 7.5 (High)
Location: src/app/api/auth/login/route.ts
Attack Vector: Brute force password attempts
Impact: Account takeover via credential stuffing
Remediation: Add rate limiting middleware (5 attempts/minute)
CVSS Score: 7.1 (High)
Location: next.config.ts
Missing:
// next.config.ts
headers: () => [
{
source: '/:path*',
headers: [
{ key: 'X-Frame-Options', value: 'DENY' },
{ key: 'X-Content-Type-Options', value: 'nosniff' },
{ key: 'Strict-Transport-Security', value: 'max-age=31536000' },
],
},
],
CVSS Score: 6.1 (High)
Location: src/components/Comment.tsx:23
Issue: User content rendered without sanitization
<div dangerouslySetInnerHTML={{ __html: comment.body }} />
Remediation:
import DOMPurify from 'dompurify';
<div dangerouslySetInnerHTML={{ __html: DOMPurify.sanitize(comment.body) }} />
CVSS Score: 5.3 (Medium)
Location: src/pages/verify.tsx:8
Attack Vector: Token visible in browser history, referrer headers
Impact: Session hijacking
Remediation: Use POST body or HTTP-only cookies for tokens
CVSS Score: 4.3 (Medium)
Location: src/app/api/settings/route.ts
Attack Vector: Forged requests from malicious sites
Impact: Unauthorized settings changes
Remediation: Add CSRF tokens to forms
CVSS Score: 5.3 (Medium)
Location: src/app/api/middleware/error.ts:15
Issue: Error responses include internal paths and stack traces
Remediation: Return generic messages in production
Location: src/app/api/debug/route.ts
Issue: Debug endpoint accessible in production
Remediation: Remove or protect with auth

## Execution Logging
After completing, append to `.claude/audits/EXECUTION_LOG.md`:
| [timestamp] | security-auditor | [status] | [duration] | [findings] | [errors] |
## Output Verification
Before completing:
1. Verify `.claude/audits/AUDIT_SECURITY.md` was created
2. Verify file has content beyond headers
3. If no issues found, write "No security issues detected" (not empty file)
**This agent is the SINGLE SOURCE for security findings. Other agents must NOT duplicate these checks.**
