| **LOW** | 12 | Nice-to-have improvements |

---

## 1. CRITICAL Issues (Must Fix Before Production)

### 1.1 Missing Input Validation [CRITICAL]

**Location**: `lib/actions.ts` (all server actions)

**Issue**: Server actions accept user input without validation. Attackers could inject malicious data or cause database errors.

**Current Code**:
```typescript
export async function createTask(formData: {
  title: string
  // ... accepts any string
}) {
  const { data, error } = await supabase.from('tasks').insert({
    title: formData.title,  // Raw input!
    // ...
  })
}
```

**Fix Required**:
```typescript
import { z } from 'zod'

const createTaskSchema = z.object({
  title: z.string().min(1).max(200).trim(),
  description: z.string().max(2000).optional(),
  type: z.enum(['task', 'chore']),
  area: z.string().max(50).optional(),
  recurrence: z.enum(['none', 'daily', 'weekly', 'biweekly', 'monthly']).default('none'),
  due_date: z.string().datetime().optional(),
})

export async function createTask(formData: unknown) {
  const parsed = createTaskSchema.safeParse(formData)
  if (!parsed.success) {
    return { error: 'Invalid input', details: parsed.error.flatten() }
  }
  // Use parsed.data
}
```

**Files to Update**:
- `lib/actions.ts` - All 30+ actions
- Add `zod` to dependencies

---

### 1.2 Secrets Not Encrypted [CRITICAL]

**Location**: `secrets` table, `integrations.config`

**Issue**: Sensitive credentials stored as plain text in database. Compromised database = compromised credentials.

**Current State**:
- `secrets.value` stores plain text
- `integrations.config` stores API keys in JSONB

**Fix Required**:
1. Add encryption layer using `@vercel/kv` or custom AES-256-GCM
2. Encrypt on write, decrypt on read
3. Store encryption key in environment variable

```typescript
import crypto from 'crypto'

const ENCRYPTION_KEY = process.env.SECRETS_ENCRYPTION_KEY! // 32 bytes

function encrypt(text: string): string {
  const iv = crypto.randomBytes(16)
  const cipher = crypto.createCipheriv('aes-256-gcm', Buffer.from(ENCRYPTION_KEY, 'hex'), iv)
  let encrypted = cipher.update(text, 'utf8', 'hex')
  encrypted += cipher.final('hex')
  const authTag = cipher.getAuthTag().toString('hex')
  return `${iv.toString('hex')}:${authTag}:${encrypted}`
}

function decrypt(encrypted: string): string {
  const [ivHex, authTagHex, encryptedText] = encrypted.split(':')
  const decipher = crypto.createDecipheriv('aes-256-gcm', Buffer.from(ENCRYPTION_KEY, 'hex'), Buffer.from(ivHex, 'hex'))
  decipher.setAuthTag(Buffer.from(authTagHex, 'hex'))
  let decrypted = decipher.update(encryptedText, 'hex', 'utf8')
  decrypted += decipher.final('utf8')
  return decrypted
}
```

---

### 1.3 Rate Limiting Missing [CRITICAL]

**Location**: All server actions, middleware

**Issue**: No rate limiting on auth endpoints or API calls. Vulnerable to:
- Brute force password attacks
- Denial of service
- Resource exhaustion

**Fix Required**:
```typescript
// middleware.ts
import { Ratelimit } from '@upstash/ratelimit'
import { Redis } from '@upstash/redis'

const ratelimit = new Ratelimit({
  redis: Redis.fromEnv(),
  limiter: Ratelimit.slidingWindow(10, '10 s'), // 10 requests per 10 seconds
})

export async function middleware(request: NextRequest) {
  const ip = request.ip ?? '127.0.0.1'
  const { success, limit, reset, remaining } = await ratelimit.limit(ip)
  
  if (!success) {
    return new NextResponse('Too Many Requests', {
      status: 429,
      headers: {
        'X-RateLimit-Limit': limit.toString(),
        'X-RateLimit-Remaining': remaining.toString(),
        'X-RateLimit-Reset': reset.toString(),
      },
    })
  }
  // Continue...
}
```

---

### 1.4 CSRF Protection Missing [CRITICAL]

**Location**: All forms

**Issue**: Forms don't include CSRF tokens. Attackers could trick users into performing actions.

**Current State**: Server actions bypass traditional CSRF but still vulnerable in some scenarios.

**Fix Required**:
1. Verify `Origin` header in server actions
2. Add CSRF token for sensitive operations

```typescript
// In server actions
export async function deleteSecret(secretId: string) {
  const headersList = headers()
  const origin = headersList.get('origin')
  const host = headersList.get('host')
  
  if (origin && !origin.includes(host!)) {
    return { error: 'Invalid origin' }
  }
  // Continue...
}
```

---

### 1.5 Admin Client Exposure Risk [CRITICAL]

**Location**: `lib/supabase/admin.ts`

**Issue**: Service role key used in several places. Any mistake could expose it to client.

**Current Usage**:
- `lib/auth-actions.ts` - createSpace, joinSpace
- Signup trigger uses SECURITY DEFINER (safe)

**Fix Required**:
1. Audit all admin client usage
2. Move admin operations to dedicated API routes
3. Add ESLint rule to prevent client-side imports

```javascript
// .eslintrc.js
module.exports = {
  rules: {
    'no-restricted-imports': [
      'error',
      {
        paths: [{
          name: '@/lib/supabase/admin',
          message: 'Admin client should only be used in API routes, not client components.',
        }],
      },
    ],
  },
}
```

---

## 2. HIGH Priority Issues

### 2.1 Social Auth Buttons Non-Functional [HIGH]

**Location**: `app/login/page.tsx`

**Issue**: GitHub and Google buttons are rendered but don't work.

**Fix**:
```typescript
async function handleGitHubLogin() {
  const supabase = createClient()
  const { error } = await supabase.auth.signInWithOAuth({
    provider: 'github',
    options: {
      redirectTo: `${window.location.origin}/auth/callback`,
    },
  })
  if (error) setError(error.message)
}
```

**Also Required**:
- Configure OAuth providers in Supabase Dashboard
- Add provider credentials

---

### 2.2 Import Feature Non-Functional [HIGH]

**Location**: `app/(app)/import/page.tsx`

**Issue**: File upload and database connector UI exists but doesn't process files.

**Fix Required**:
1. Add file input handler
2. Implement CSV parser (use `papaparse`)
3. Add column mapping logic
4. Implement batch insert

```typescript
'use client'
import Papa from 'papaparse'
import { importMembers } from '@/lib/actions'

function handleFileUpload(event: React.ChangeEvent<HTMLInputElement>) {
  const file = event.target.files?.[0]
  if (!file) return

  Papa.parse(file, {
    header: true,
    complete: async (results) => {
      const mappedRows = results.data.map(row => ({
        display_name: row['Full Name'],
        email: row['Email'],
        // ... map other fields
      }))
      const result = await importMembers(mappedRows)
      // Handle result
    },
    error: (error) => setError(error.message),
  })
}
```

---

### 2.3 Payment Platform Integrations [HIGH]

**Location**: `app/(app)/settings/settings-client.tsx`

**Issue**: PayPal, Zeffy, Venmo integrations are UI-only. No actual API connections.

**Status**: 
- Integration config storage works
- No OAuth flows
- No transaction sync
- No webhooks

**Required Work**:
1. PayPal: Implement OAuth 2.0, transaction API
2. Zeffy: Implement API key auth, webhook handler
3. Venmo: Research Business API availability

---

### 2.4 Webhook Endpoint Missing [HIGH]

**Location**: Settings shows webhook URL but no endpoint exists

**Issue**: URL `https://api.hackerspace.sh/{slug}/members` is displayed but endpoint doesn't exist.

**Fix Required**:
```typescript
// app/api/[slug]/members/route.ts
import { createAdminClient } from '@/lib/supabase/admin'
import { headers } from 'next/headers'
import crypto from 'crypto'

export async function POST(
  request: Request,
  { params }: { params: { slug: string } }
) {
  const headersList = headers()
  const signature = headersList.get('x-webhook-signature')
  
  const admin = createAdminClient()
  const { data: space } = await admin
    .from('spaces')
    .select('id, webhook_secret')
    .eq('slug', params.slug)
    .single()

  if (!space || !space.webhook_secret) {
    return Response.json({ error: 'Invalid space' }, { status: 404 })
  }

  // Verify signature
  const body = await request.text()
  const expectedSignature = crypto
    .createHmac('sha256', space.webhook_secret)
    .update(body)
    .digest('hex')

  if (signature !== expectedSignature) {
    return Response.json({ error: 'Invalid signature' }, { status: 401 })
  }

  // Process webhook payload
  const data = JSON.parse(body)
  // ...

  return Response.json({ success: true })
}
```

---

### 2.5 Error Boundaries Missing [HIGH]

**Location**: All pages

**Issue**: No error boundaries. Unhandled errors crash entire app.

**Fix Required**:
```typescript
// app/(app)/error.tsx
'use client'

export default function Error({
  error,
  reset,
}: {
  error: Error & { digest?: string }
  reset: () => void
}) {
  return (
    <div className="min-h-screen flex items-center justify-center">
      <div className="text-center">
        <h2 className="text-xl font-semibold mb-2">Something went wrong</h2>
        <p className="text-muted-foreground mb-4">{error.message}</p>
        <button onClick={reset} className="bg-primary text-white px-4 py-2 rounded">
          Try again
        </button>
      </div>
    </div>
  )
}
```

---

### 2.6 Loading States Inconsistent [HIGH]

**Location**: Multiple pages

**Issue**: Some pages have loading states, others show blank while data loads.

**Fix Required**: Add loading.tsx to all route groups:
```typescript
// app/(app)/loading.tsx
export default function Loading() {
  return (
    <div className="min-h-screen flex items-center justify-center">
      <Spinner className="w-8 h-8" />
    </div>
  )
}
```

---

### 2.7 Session Refresh Issues [HIGH]

**Location**: Long-running sessions

**Issue**: Session may expire during use without proper refresh.

**Current**: Middleware calls `updateSession` but client components don't handle expiry.

**Fix Required**:
```typescript
// Add to layout or hook
useEffect(() => {
  const { data: { subscription } } = supabase.auth.onAuthStateChange((event) => {
    if (event === 'SIGNED_OUT' || event === 'TOKEN_REFRESHED') {
      router.refresh()
    }
  })
  return () => subscription.unsubscribe()
}, [])
```

---

### 2.8-2.12 Additional HIGH Issues

| Issue | Location | Description |
|-------|----------|-------------|
| No email notifications | - | Members not notified of approvals, assignments |
| Task recurrence not auto-resetting | Tasks | Recurring tasks don't auto-create new instances |
| Project task linking missing | Projects | Can't link tasks to projects |
| Area leads not editable | Ops | UI shows leads but no edit functionality |
| Knowledge base detail page missing | `/ops/[id]` | Links go to non-existent page |

---

## 3. MEDIUM Priority Issues

### 3.1 TypeScript Strict Mode Disabled

**Location**: `tsconfig.json`

**Issue**: Not using strict mode reduces type safety.

**Fix**: Enable strict mode and fix resulting errors.

---

### 3.2 No Test Coverage

**Issue**: Zero tests exist.

**Required**:
- Unit tests for all server actions (Vitest)
- Component tests (React Testing Library)
- E2E tests for critical flows (Playwright)

---

### 3.3 No Logging/Monitoring

**Issue**: No structured logging or error tracking.

**Fix**: Add Sentry, LogRocket, or similar.

---

### 3.4 Database Queries Not Optimized

**Issue**: Some pages make sequential queries that could be parallel.

**Example Fix**:
```typescript
// Before: Sequential
const { data: tasks } = await supabase.from('tasks').select('*')
const { data: projects } = await supabase.from('projects').select('*')

// After: Parallel
const [{ data: tasks }, { data: projects }] = await Promise.all([
  supabase.from('tasks').select('*'),
  supabase.from('projects').select('*'),
])
```
