feat: Implement comprehensive security hardening
Security Improvements: - Auto-generate AUTH_SECRET and admin credentials on first launch - Cryptographically secure random generation - Stored in database for persistence - Logged once to container logs for admin retrieval - Implement CSRF protection with double-submit cookie pattern - Three-way validation: cookie, header, and session database - Automatic client-side injection via plugin - Server middleware for automatic validation - Zero frontend code changes required - Add session fixation prevention with automatic invalidation - Regenerate sessions on password changes - Keep current session active, invalidate others on profile password change - Invalidate ALL sessions on forgot-password reset - Invalidate ALL sessions on admin password reset - Upgrade password reset codes to 8-char alphanumeric - Increased from 1M to 1.8 trillion combinations - Uses crypto.randomInt() for cryptographic randomness - Excluded confusing characters (I, O) for better UX - Case-insensitive verification - Implement dual-layer account lockout - IP-based rate limiting (existing) - Per-account lockout: 10 attempts = 30 min lock - Automatic unlock after expiration - Admin manual unlock via UI - Visual status indicators in users table Database Changes: - Add csrf_token column to sessions table - Add failed_login_attempts and locked_until columns to users table - Add settings table for persistent AUTH_SECRET storage - All migrations backward-compatible with try-catch New Files: - server/utils/csrf.ts - CSRF protection utilities - server/middleware/csrf.ts - Automatic CSRF validation middleware - plugins/csrf.client.ts - Automatic CSRF header injection - server/api/users/unlock/[id].post.ts - Admin unlock endpoint Modified Files: - server/utils/database.ts - Core security functions and schema updates - server/utils/email.ts - Enhanced reset code generation - server/api/auth/login.post.ts - CSRF + account lockout logic - server/api/auth/register.post.ts - CSRF token generation - server/api/auth/logout.post.ts - CSRF cookie cleanup - server/api/auth/reset-password.post.ts - Session invalidation - server/api/auth/verify-reset-code.post.ts - Case-insensitive codes - server/api/profile/update.put.ts - Session invalidation on password change - server/api/users/password/[id].put.ts - Session invalidation on admin reset - pages/users.vue - Lock status display and unlock functionality - docker-compose.yml - Removed default credentials - nuxt.config.ts - Support auto-generation All changes follow OWASP best practices and are production-ready. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
