Security Improvements Implemented

JWT Secret Persistence

  • ✅ 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

  • ✅ Fixed broken thumbnails/images
  • ✅ Created get_current_user_media() dependency

Testing Performed

Authentication Testing

# 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

# 6 rapid login requests
Request 1-3: Valid response ✓
Request 4-6: Rate limit exceeded ✓

Service Status

sudo systemctl status media-downloader-api
→ Active (running) ✓
