 # 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 the `CSRF_SECRET` environment variable to the same value across all instances.
 ```bash
 # Generate a secure secret
 openssl rand -base64 32
 ```
 ```yaml
 # docker-compose.yml or k8s deployment
 backend:
  environment:
    - 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.

  - Docker Compose: Add CSRF_SECRET=<your-secret> to the backend service environment
  - Kubernetes: Add to your ConfigMap/Secret and reference in the backend deployment
  If not set, the backend will refuse to start.

 # 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**
