# Security Fixes TODO
Статус исправлений критических уязвимостей из аудита безопасности.
---
## 🔴 КРИТИЧЕСКИЕ (В РАБОТЕ)
### Безопасность API
- [ ] **Rate Limiting** - защита от brute force атак
- [ ] Установить slowapi
- [ ] Добавить rate limiting на login (5/минуту)
- [ ] Добавить rate limiting на register (3/час)
- [ ] Добавить rate limiting на uploads (100/час)
### Аутентификация
- [ ] **Token Revocation** - logout должен удалять токен
- [ ] Создать Redis client для blacklist
- [ ] Добавить проверку blacklist в get_current_user
- [ ] Реализовать endpoint /auth/logout
- [ ] **Refresh Token Rotation** - обновление токенов
- [ ] Endpoint /auth/refresh
- [ ] Отзыв старого refresh token при rotation
- [ ] Frontend interceptor для автообновления
- [ ] **Account Lockout** - блокировка после 3 попыток на сутки
- [ ] LoginAttemptTracker с Redis
- [ ] Проверка блокировки перед login
- [ ] Запись неудачных попыток
### Storage Management
- [ ] **Storage Quota** - 3GB по пользователю
- [ ] Миграция: добавить storage_quota_bytes и storage_used_bytes в User
- [ ] Проверка квоты при create_upload
- [ ] Увеличение used_bytes при finalize_upload
- [ ] Уменьшение used_bytes при delete (S3 trash)
- [ ] Endpoint GET /users/me/storage для статистики
### Валидация файлов
- [ ] **Content-Type Whitelist** - только разрешенные типы
- [ ] ALLOWED_IMAGE_TYPES whitelist
- [ ] ALLOWED_VIDEO_TYPES whitelist
- [ ] Обновить validator в schemas.py
- [ ] **Magic Bytes Verification** - проверка реального типа файла
- [ ] Установить python-magic
- [ ] Проверка при finalize_upload
- [ ] Удаление файла из S3 при несовпадении
### File Upload Security
- [ ] **Streaming Chunks** - предотвратить OOM
- [ ] Метод upload_fileobj_streaming в S3Client
- [ ] Обновить upload_file_to_s3 для стриминга
- [ ] Проверка размера ПЕРЕД чтением (макс 3GB)
### ZIP Download
- [ ] **ZIP Streaming** - не держать весь архив в памяти
- [ ] Создание ZIP в temp файле
- [ ] FileResponse вместо возврата bytes
- [ ] BackgroundTask для удаления temp файла
### Configuration
- [ ] **Trash Bucket Config** - убрать hardcode
- [ ] Добавить TRASH_BUCKET в config.py
- [ ] Использовать из конфига в S3Client
### HTTP Security
- [ ] **Security Headers** - защита от XSS, clickjacking
- [ ] SecurityHeadersMiddleware
- [ ] X-Frame-Options, X-Content-Type-Options
- [ ] CSP, HSTS, Referrer-Policy
### Architecture
- [ ] **FolderService Refactoring** - разделить обязанности
- [ ] Убрать прямую работу с AssetRepository
- [ ] Создать FolderManagementService для оркестрации
- [ ] Использовать AssetService methods
### Search
- [ ] **Asset Search** - поиск по имени файла
- [ ] Метод search_assets в AssetRepository
- [ ] Endpoint GET /assets/search
- [ ] Поддержка ILIKE для поиска
---
## 🟡 TODO (ОТЛОЖЕНО НА ПОТОМ)
- [ ] JWT Secret Validation - проверка слабого секрета в продакшене
- [ ] S3 Encryption at Rest - ServerSideEncryption='AES256'
- [ ] Share Token Uniqueness Check - collision detection
- [ ] CSRF Protection - fastapi-csrf-protect
- [ ] Strong Password Validation - complexity requirements
- [ ] Database Indexes - composite indexes для производительности
- [ ] Foreign Keys - relationships в models
- [ ] Password Reset Flow - forgot/reset endpoints + email
- [ ] EXIF Metadata Extraction - captured_at, dimensions
- [ ] Database Backups - автоматизация бэкапов
- [ ] Comprehensive Testing - 70%+ coverage
- [ ] Monitoring & Logging - structured logging, metrics
- [ ] CI/CD Pipeline - GitHub Actions
---
## 📊 Progress
**Выполнено:** 14/14 критических задач ✅✅✅
**Статус:** 🎉 ВСЕ ЗАДАЧИ ЗАВЕРШЕНЫ!
### ✅ Завершено:
1. ✅ slowapi добавлен в pyproject.toml
2. ✅ Config обновлен (trash_bucket, max 3GB, default quota)
3. ✅ Redis client создан (TokenBlacklist, LoginAttemptTracker)
4. ✅ main.py: Rate limiting, Security Headers, CORS restrictive
5. ✅ User model: storage_quota_bytes, storage_used_bytes
6. ✅ Миграция 002: add_storage_quota создана
7. ✅ schemas.py: Content-Type whitelist, 3GB max, RefreshTokenRequest, StorageStatsResponse
8. ✅ dependencies.py: blacklist check в get_current_user
9. ✅ auth.py: rate limiting на endpoints, logout, refresh, account lockout, storage stats
10. ✅ S3Client: streaming upload (upload_fileobj_streaming), trash_bucket from config
11. ✅ asset_service: storage quota check, streaming (upload_fileobj_streaming), magic bytes verification, storage_used_bytes updates
12. ✅ batch_operations: ZIP streaming (temp file + FileResponse + BackgroundTasks cleanup), storage_used_bytes updates
13. ✅ FolderService: refactored (removed asset modification, only read-only validation queries)
14. ✅ AssetRepository + AssetService + API: search_assets method (ILIKE), GET /api/v1/assets/search endpoint
