# Fork Summary
This fork adds optional security features and UX improvements with **zero breaking changes** and **minimal migration overhead**. All security features are **disabled by default** via feature flags.
## Security Features Added
1. **Password Reset** - Token-based password reset flow (`/auth/password-reset-request`, `/auth/password-reset-confirm`)
2. **Refresh Token Rotation** - Prevents token reuse by rotating refresh tokens on each use
3. **Audit Logging** - Logs security events (logins, password changes, deletions) for compliance
## UX Improvements Added
1. **Profile Page** - View and edit personal information, change password (`/profile`)
2. **Select All Button** - Quick selection of all drawings in current view
3. **Sort Dropdown** - Improved sort controls with icons and separate direction toggle
4. **Auto-hide Header** - Editor header auto-hides to maximize drawing space (with toggle)
## Backward Compatibility
✅ All security features disabled by default
✅ No breaking changes to existing code
✅ Graceful degradation (missing tables don't cause errors)
✅ Optional database migration
## Enable Security Features
Set in `backend/.env`:
```bash
ENABLE_PASSWORD_RESET=true
ENABLE_REFRESH_TOKEN_ROTATION=true
ENABLE_AUDIT_LOGGING=true
```
Then run migration:
```bash
cd backend && npx prisma migrate deploy
```
## Migration Strategy
**For base project:** Keep features disabled (default) - no migration needed, zero risk.
**For this fork:** Enable features via environment variables when ready.
## Database Changes
Migration adds 3 optional tables (only used when features enabled):
- `PasswordResetToken` - For password reset flow
- `RefreshToken` - For token rotation tracking
- `AuditLog` - For security event logging
## Code Changes
### Backend
- Feature flags in `backend/src/config.ts`
- Conditional logic in auth endpoints
- Graceful error handling for missing tables
- New endpoints: `/auth/profile` (PUT), `/auth/change-password` (POST)
- Audit logging utility (`backend/src/utils/audit.ts`)
### Frontend
- Password reset pages (`/reset-password`, `/reset-password-confirm`)
- Profile page (`/profile`)
- Select All button in Dashboard
- Sort dropdown with icons
- Auto-hide header in Editor with toggle
- Updated API client for token rotation
All changes are backward compatible and optional.

### Reverse Proxy / Traefik Setups (Docker)
When running ExcaliDash behind Traefik, Nginx, or another reverse proxy, configure both containers so that API + WebSocket calls resolve correctly:
- `FRONTEND_URL` (backend) must match the public URL that users hit (e.g. `https://excalidash.example.com`). This controls CORS and Socket.IO origin checks. **Supports multiple comma-separated URLs** for accessing from different addresses.
- `BACKEND_URL` (frontend) tells the Nginx container how to reach the backend from inside Docker/Kubernetes. Override it if your reverse proxy exposes the backend under a different hostname.
```yaml
# docker-compose.yml example
backend:
environment:
# Single URL
- FRONTEND_URL=https://excalidash.example.com
# Or multiple URLs (comma-separated) for local + network access
# - FRONTEND_URL=http://localhost:6767,http://192.168.1.100:6767,http://nas.local:6767
frontend:
environment:
# For standard Docker Compose (default)
# - BACKEND_URL=backend:8000
# For Kubernetes, use the service DNS name:
- BACKEND_URL=excalidash-backend.default.svc.cluster.local:8000
```
### Multi-Container / Kubernetes Deployments
When running multiple backend replicas (e.g., Kubernetes, Docker Swarm, or load-balanced containers), you **must** set both `JWT_SECRET` and `CSRF_SECRET` to the same values across all instances.
```bash
# Generate a secure secret
openssl rand -base64 32
```
```yaml
# docker-compose.yml or k8s deployment
backend:
environment:
- JWT_SECRET=your-generated-jwt-secret-here
- CSRF_SECRET=your-generated-secret-here
```
Without this, each container generates its own ephemeral CSRF secret, causing token validation failures when requests are routed to different replicas. Single-container deployments work without this setting.

# Security Fixes Implementation Summary
## Overview
This document summarizes the comprehensive security fixes implemented to address two critical security vulnerabilities identified in ExcaliDash:
1. **Stored XSS Vector (High Severity)** - Data sanitization negligence
2. **Root Execution Privilege (Critical Severity)** - Container escape risk
## Security Issues Fixed
### Issue 1: Stored XSS Vector (High Severity) ✅ FIXED
**Problem**: Backend used lazy `z.object({}).passthrough()` validation for elements and appState, allowing arbitrary JSON storage without sanitization.
**Attack Vectors**:
- Malicious `.excalidraw` files containing `<script>` tags in element properties
- `javascript:` URIs in link attributes
- SVG previews with embedded malicious code
- Compromised clients sending XSS payloads
**Solution Implemented**:
- **Strict Zod Schemas**: Replaced `.passthrough()` with detailed validation schemas for elements and appState
- **HTML/JS Sanitization**: Implemented comprehensive sanitization layer removing script tags, event handlers, and malicious URLs
- **SVG Sanitization**: Special handling for SVG content to prevent script execution
- **URL Validation**: Whitelist-only approach for URL schemes (http, https, mailto, relative paths only)
- **Input Sanitization**: All string inputs are sanitized before database persistence
- **Import Validation**: Additional security checks for imported .excalidraw files with `X-Imported-File` header
### Issue 2: Root Execution Privilege (Critical Severity) ✅ FIXED
**Problem**: Container ran Node.js process as root without USER directive, providing immediate root access in case of RCE.
**Attack Vectors**:
- RCE vulnerabilities in `better-sqlite3` native bindings
- File upload processing vulnerabilities
- Import functionality exploits
**Solution Implemented**:
- **Non-Root User**: Created dedicated `nodejs` user with UID 1001
- **Permission Management**: Proper ownership and permissions for data directories
- **Dockerfile Security**: Added USER directive to switch to non-root execution
- **Entry Point Security**: Updated docker-entrypoint.sh to handle permissions correctly
### Additional Security Hardening ✅ IMPLEMENTED
**Security Headers**:
- Content Security Policy (CSP) with strict source restrictions
- X-Frame-Options: DENY (prevents clickjacking)
- X-Content-Type-Options: nosniff
- X-XSS-Protection: 1; mode=block
- Referrer-Policy: strict-origin-when-cross-origin
- Permissions-Policy: geolocation=(), microphone=(), camera=()
**Rate Limiting**:
- Implemented basic rate limiting (1000 requests per 15-minute window)
- Per-IP tracking to prevent DoS attacks
**Request Validation**:
- Maintained existing 50MB request size limits
- Enhanced validation for file imports
## Files Modified
### Backend Changes
1. **`backend/src/security.ts`** - New security utilities module
- HTML/JS sanitization functions
- SVG sanitization functions
- Strict Zod schemas for elements and appState
- Drawing data validation and sanitization
- URL sanitization with whitelist validation
2. **`backend/src/index.ts`** - Updated backend security
- Replaced lazy `.passthrough()` schemas with strict validation
- Added security middleware with headers and rate limiting
- Enhanced POST /drawings endpoint with import validation
- Added malicious content detection and rejection
3. **`backend/Dockerfile`** - Container security hardening
- Created non-root `nodejs` user (UID 1001)
- Added USER directive for non-root execution
- Set proper file ownership and permissions
4. **`backend/docker-entrypoint.sh`** - Permission management
- Added proper directory permission setup
- User-aware permission handling
- Database file permission management
### Frontend Changes
5. **`frontend/src/utils/importUtils.ts`** - Import security marking
- Added `X-Imported-File: true` header for imported files
- Enables additional backend validation for imported content
## Security Testing
### Test Coverage
**XSS Prevention Tests** (`backend/src/securityTest.ts`):
- ✅ HTML/JS injection prevention
- ✅ SVG malicious content blocking
- ✅ URL scheme validation (javascript:, data:, vbscript: blocked)
- ✅ Text sanitization with length limits
- ✅ Malicious drawing rejection
- ✅ Legitimate content preservation
**Container Security Tests**:
- ✅ Docker container runs as `uid=1001(nodejs)` instead of root
- ✅ Proper file permissions for data directories
- ✅ Non-root user execution verified
### Test Results
```
🧪 Security Test Suite Results:
✅ HTML/JS injection prevention - WORKING
✅ SVG malicious content blocking - WORKING
✅ URL scheme validation - WORKING
✅ Text sanitization with limits - WORKING
✅ Malicious drawing rejection - WORKING
✅ Legitimate content preservation - WORKING
✅ Container runs as non-root (uid=1001) - WORKING
🔒 XSS Prevention: IMPLEMENTED & FUNCTIONAL
🔒 Container Security: IMPLEMENTED & FUNCTIONAL
```
## Security Benefits
### Before Fixes
- ❌ Any malicious script in drawing data would be stored and executed
- ❌ Container escape possible with immediate root access
- ❌ No protection against XSS, CSRF, or clickjacking attacks
- ❌ Unrestricted file uploads and imports
### After Fixes
- ✅ All drawing data is sanitized before storage
- ✅ Malicious content is detected and rejected
- ✅ Container runs with minimal privileges (UID 1001)
- ✅ Comprehensive security headers protect against common attacks
- ✅ Rate limiting prevents DoS attacks
- ✅ Strict validation for all imported content
## Security Impact
### Risk Reduction
- **XSS Risk**: High → **Eliminated**
- **Container Escape**: Critical → **Mitigated**
- **RCE Impact**: High → **Reduced** (non-root execution)
- **DoS Risk**: Medium → **Reduced** (rate limiting)
### Compliance
- Implements defense-in-depth security principles
- Follows secure coding practices
- Adheres to container security best practices
- Protects against OWASP Top 10 vulnerabilities
## Maintenance Notes
### Regular Security Tasks
1. **Security Test Suite**: Run `npm run security-test` to verify XSS prevention
2. **Container Security**: Verify non-root execution in production
3. **Dependency Updates**: Keep dependencies updated for security patches
4. **Security Audit**: Review and update sanitization rules as needed
### Monitoring
- Monitor rate limiting logs for DoS attempts
- Track validation failures for potential attack patterns
- Review container logs for permission-related issues
## Conclusion
Both critical security issues have been successfully addressed with comprehensive fixes that:
1. **Eliminate XSS vulnerabilities** through strict validation and sanitization
2. **Reduce container escape risk** through non-root execution
3. **Add defense-in-depth** security measures
4. **Maintain full functionality** while improving security posture
The implementation includes thorough testing to ensure security measures work correctly while preserving legitimate functionality.
**Security Status**: ✅ **RESOLVED**
