Critical security and robustness fixes from a code audit:
- WS terminal/VNC now require a JWT (?token=), validate the session,
vms.console permission and VM ownership before bridging to Proxmox
(previously the LXC terminal gave unauthenticated root shell access).
Frontend ConsolePage passes the token in both WS URLs.
- Fix SSH fallback for `pvecm delnode`: SSHClient now supports password
auth (it previously crashed with TypeError); ProxmoxClient stores the
password for SSH fallbacks and the host port suffix is stripped.
- Add production startup warnings for default ADMIN_PASSWORD and wildcard
CORS_ORIGINS.
- dashboard: use tz-aware utcnow() instead of naive datetime.utcnow().
- crypto: narrow decrypt_value except to InvalidToken and log failures.
- ssh_client: guard the shared connection cache with a lock; make
unknown-host-key rejection opt-in via SSH_REJECT_UNKNOWN_HOSTS.
- logging: send loguru console output to stderr instead of stdout.
- Sync version fallback to 1.5.1; remove one-off refactor scripts.
- Add CODE_REVIEW.md audit report.

- AttributeError: OSTemplate has no 'template_vmid' field; the actual column is 'vmid'.
- Use OSTemplate.get_vmid_for_node() to support cross-node replicated templates,
falling back to source_node/vmid otherwise.
- VMInstance.memory is stored in bytes, but Proxmox config expects MB.
- Migration 20: user_servers association table (User ↔ ProxmoxServer)
- API: GET/PUT /api/users/{id}/servers — assign servers to users with workspace-conflict validation
- API: GET /api/users/{id}/server-assignments — enriched server list (assigned + compatible flags)
- Non-admin server filter: intersection of assigned_servers and workspace servers
- Migration 21: dashboard:view = false for user role (new key format)
- Migration 22: proxmox.cluster.manage → cluster:manage for admin role
- API: GET/PUT /api/{server_id}/vm/{vmid}/owner — VM/LXC owner assignment (admin-only)
- Login: smart redirect based on user permissions after authentication
- Login: returnUrl param support for post-login redirect
- Roles API: user_count field per role in GET /api/roles
- node_uptime added to server detail API response
- Remove redundant PermissionChecker from GET /users HTML route
- Fix all `from ..` → `from ...` in app/api/proxmox/*.py after the
proxmox.py split (PR #6) placed modules one level deeper, causing
ModuleNotFoundError on startup
- Broaden Content-Security-Policy to allow CDN sources used in templates:
cdnjs.cloudflare.com (Font Awesome), cdn.jsdelivr.net (Bootstrap,
Chart.js, xterm), fonts.googleapis.com/gstatic.com (Google Fonts),
esm.sh (noVNC) — the overly-strict CSP was blocking all icons and
charts from loading in the browser

Encrypt Proxmox server passwords and VM cloud-init passwords in the database:
- Add backend/app/crypto.py: Fernet-based encrypt/decrypt helpers + EncryptedString
SQLAlchemy TypeDecorator (transparent to all existing code, no API changes)
- Add FERNET_KEY config field (env var); without it values stay plaintext for
backward compatibility, with a logged warning
- Update models.py: ProxmoxServer.password and VMInstance.cloud_init_password
now use EncryptedString(255) instead of String(255)
- Add migration 14 in migrations/migrations.py: idempotent re-encryption of
existing plaintext rows (skipped when FERNET_KEY is not set)
CSRF analysis:
- /api/auth/change-password is protected by JWT Bearer token (Authorization header)
- Browsers cannot auto-include Authorization headers cross-site → CSRF is not
applicable here; added explanatory comment
Improve migration loading:
- Add migrations/__init__.py to make it a proper Python package
- Replace fragile importlib dynamic loading in main.py with a standard import

Critical fixes:
- init_admin.py: replace hardcoded admin123 password with ADMIN_PASSWORD env var
- proxmox_client.py, models.py: change verify_ssl default from False to True
- api/proxmox.py: use server.verify_ssl instead of hardcoded verify=False in websocket handler
- ssh_client.py: replace AutoAddPolicy (MITM-vulnerable) with WarningPolicy + load_system_host_keys
Security hardening:
- main.py: add security headers middleware (CSP, X-Frame-Options, HSTS, X-XSS-Protection, Referrer-Policy)
- main.py: fix CORS — allow_credentials=True is incompatible with allow_origins=["*"]; read origins from CORS_ORIGINS env var
- auth.py, logging_middleware.py: validate X-Forwarded-For/X-Real-IP to prevent IP spoofing
Performance:
- monitoring_worker.py: wire up cleanup_expired_connections() as hourly scheduled job (was defined but never called)
Code quality:
- logging_service.py: move `import json` from inside function to module level
- ssh_client.py, proxmox_client.py, api/proxmox.py, rbac/migration.py, task_queue_service.py: replace all bare `except:` with `except Exception:`
- .env.example, config.py: document ADMIN_PASSWORD and CORS_ORIGINS settings

- Updated `backend/app/main.py`: Added automatic execution of `/app/init_admin.py` during application startup to create default admin account
- Modified `.gitignore`: Removed `.env` from ignored files to ensure environment configuration is available during deployment
- Enhanced `lifespan` context manager: Integrated admin initialization with proper error handling and logging
- Improved startup reliability: Ensures default credentials are provisioned regardless of deployment environment
The fix ensures that new deployments automatically set up the default admin user, resolving widespread issues with missing login credentials. The change is robust, idempotent, and logs all initialization steps for debugging.
