Keith SmithandClaude Sonnet 4.5 e7fbef75e9 Fix HIGH Security Issue: Require ALLOWED_HOSTS in production
Added validation to ensure ALLOWED_HOSTS is explicitly set in production.

Changes:
- Check if ALLOWED_HOSTS environment variable is set
- Raise ValueError with helpful message if not set
- Use os.environ['ALLOWED_HOSTS'] instead of .get() to enforce requirement
- Prevents empty or missing ALLOWED_HOSTS from bypassing host validation

Security impact:
- Prevents host header injection attacks
- Blocks cache poisoning via host header manipulation
- Ensures production deployments have explicit allowed hosts configured
- Fails fast with clear error message if misconfigured

Keith SmithandClaude Sonnet 4.5 5d9c901918 Fix HIGH Security Issue: Add file upload validation for avatars
Added comprehensive validation for avatar file uploads to prevent malicious file uploads.

Validation Checks:
- File extension: Only allow jpg, jpeg, png, gif
- File size: Maximum 5MB
- Content type: Verify MIME type matches allowed image types

Changes:

users/serializers.py:
- Added MAX_AVATAR_SIZE constant (5MB)
- Created validate_avatar() method in UserSerializer
- Validates file extension against whitelist
- Checks file size and provides helpful error messages
- Verifies content-type header matches allowed image types

config/settings/base.py:
- Added FILE_UPLOAD_MAX_MEMORY_SIZE = 5MB
- Added DATA_UPLOAD_MAX_MEMORY_SIZE = 5MB
- Enforces global upload limits at Django level

Security impact:
- Prevents upload of executables, malware, or scripts
- Mitigates DoS via large file uploads
- Ensures only valid image files can be uploaded
- Protects against MIME-type confusion attacks

Keith SmithandClaude Sonnet 4.5 deabe6ab3d Fix Critical Security Issue: Implement rate limiting on API endpoints
Added comprehensive rate limiting to prevent abuse and DoS attacks:

Configuration (config/settings/base.py):
- Anon rate: 100 requests/hour for anonymous users
- User rate: 1000 requests/hour for authenticated users
- Login rate: 10 attempts/hour (prevents brute force)
- Register rate: 5 attempts/hour (prevents account spam)
- Sync rate: 100 requests/hour (prevents sync flooding)

Custom throttle classes (users/throttles.py):
- LoginRateThrottle: Strict limit for login endpoint
- RegisterRateThrottle: Strict limit for registration endpoint
- SyncRateThrottle: Moderate limit for sync endpoint

Applied throttling to sensitive endpoints:
- users.views.RegisterAPIView: 5/hour
- users.views.TokenObtainPairView: 10/hour
- sync.views.sync: 100/hour

All other API endpoints use default throttles (anon: 100/hour, user: 1000/hour).

Keith SmithandClaude Sonnet 4.5 a22c3eed50 Fix Critical Security Issue: Remove weak default SECRET_KEY
Security improvements:
- selfhosted.py: Require SECRET_KEY environment variable (raises ValueError if not set)
- selfhosted.py: Validate SECRET_KEY length (minimum 50 characters)
- selfhosted.py: Warn if DEBUG=True in self-hosted mode
- development.py: Auto-generate random SECRET_KEY on each startup if not provided
- development.py: Remove production domain from ALLOWED_HOSTS
- development.py: Make CSRF_TRUSTED_ORIGINS environment-only

This prevents weak/default SECRET_KEYs from being used in production.
