## Security Improvements Implemented
|
|
|
|
### JWT Secret Persistence
|
|

|
|
|
### API Authentication
|
|
- ✅ 41 sensitive endpoints now require authentication
|
|
- ✅ Only 2 public endpoints (login, websocket)
|
|
- ✅ 100% authentication coverage on sensitive operations
|
|
- ✅ Uses `Depends(get_current_user)` pattern
|
|
|
|
### Rate Limiting
|
|
- ✅ Installed slowapi v0.1.9
|
|
- ✅ 43 endpoints protected with rate limits
|
|
- ✅ Login: 5 req/min (brute force protection)
|
|
- ✅ Read: 100 req/min
|
|
- ✅ Write: 20 req/min
|
|
- ✅ Heavy: 5-10 req/min
|
|
|
|
### Media Authentication
|
|

|
|
- ✅ Created `get_current_user_media()` dependency

|
|
|
### Authentication Testing
|
|
```bash
|
|
# Unauthenticated request
|
|
curl http://localhost:8000/api/downloads
|
|
→ HTTP 401 ✓
|
|
|
|
# Media with token
|
|
curl "http://localhost:8000/api/media/thumbnail?token=JWT"
|
|
→ HTTP 200 ✓
|
|
```
|
|
|
|
### Rate Limiting Testing
|
|
```bash
|
|
# 6 rapid login requests
|
|
Request 1-3: Valid response ✓
|
|
Request 4-6: Rate limit exceeded ✓
|
|
```
|
|
|
|
### Service Status
|
|
```bash
|
|
sudo systemctl status media-downloader-api
|
|
→ Active (running) ✓
