SurfSense Security & Architecture Audit Report

Audit Date: 2025-11-17 Audited By: Claude AI Assistant (Anthropic) Repository: https://github.com/okapteinis/SurfSense Branch: claude/surfsense-audit-automation-01MeVuvAybnL5NXHG5W3XuXe Upstream: https://github.com/MODSetter/SurfSense Session Topic: Comprehensive Security, Architecture, and Compliance Audit

Executive Summary

This report documents a comprehensive security and architecture audit of the SurfSense repository. SurfSense is an AI-powered research agent and personal knowledge base system that integrates with various external sources (Slack, Linear, GitHub, Notion, etc.) and supports local/cloud LLM deployments.

Overall Assessment: ✅ GOOD with recommendations for enhancement

The codebase demonstrates strong security practices with automated tooling (detect-secrets, pre-commit hooks, bandit), modern architecture (FastAPI + Next.js), and comprehensive documentation. Several recommendations are provided to further strengthen security posture and automation capabilities.

1. Scope of Audit

1.1 What Was Checked

✅ Security & Secrets Scanning

Scanned all source files for hardcoded credentials, API keys, tokens
Reviewed .env.example files for placeholder safety
Validated .gitignore coverage for sensitive files
Analyzed pre-commit hooks and detect-secrets baseline
Checked for exposed private keys, certificates, database credentials

✅ Architecture & LLM/RAG Components

Reviewed FastAPI backend architecture
Analyzed hybrid search implementation (vector + full-text)
Examined LangGraph agent configurations
Validated embedding models and reranker setup
Assessed PostgreSQL/pgvector integration
Reviewed Celery/Redis async task architecture

✅ Platform Compatibility

Python version requirements (3.12+)
Node.js/npm package versions
Docker containerization setup
Multi-platform support (x86_64, ARM)

✅ Licensing & Copyright

Scanned all LICENSE files
Checked for license headers in source files
Verified third-party dependency licenses

✅ Documentation Quality

Reviewed README.md, CONTRIBUTING.md
Examined setup guides (Chinese LLM guide, etc.)
Validated configuration examples

2. Security Audit Results

2.1 Secrets & Credentials Analysis

✅ Status: SECURE - No Real Secrets Found

Findings:

All API keys in codebase are placeholders:
- .env.example files use obvious placeholders:
  - SECRET_KEY=SECRET
  - GOOGLE_OAUTH_CLIENT_ID=924507538m (partial/example)
  - FIRECRAWL_API_KEY=fcr-01J0000000000000000000000 (zeros)
  - UNSTRUCTURED_API_KEY=Tpu3P0U8iy (short placeholder)
  - LLAMA_CLOUD_API_KEY=llx-nnn (obvious placeholder)
Configuration templates are safe:
- surfsense_backend/app/config/global_llm_config.example.yaml uses:
  - sk-your-openai-api-key-here
  - sk-ant-your-anthropic-api-key-here
  - your-deepseek-api-key-here
Documentation examples use masked placeholders:
- docs/chinese-llm-setup.md uses sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
No .env files committed:
- Only .env.example files present (verified with ls -la)
- Real .env files properly gitignored

✅ Security Tooling in Place

Excellent automated security measures:

detect-secrets (v1.5.0) with comprehensive detectors:
- ✅ AWS Key Detector
- ✅ Azure Storage Key Detector
- ✅ GitHub Token Detector
- ✅ JWT Token Detector
- ✅ Private Key Detector
- ✅ Slack Detector
- ✅ Discord Bot Token Detector
- ✅ High Entropy String Detectors (Base64, Hex)
- ✅ And 15+ more detectors
- Baseline file: .secrets.baseline (currently clean: "results": {})
Pre-commit hooks (.pre-commit-config.yaml):
- ✅ Secret detection on every commit
- ✅ Bandit (Python security linter) - high severity checks
- ✅ Ruff (Python linting + formatting)
- ✅ Biome (TypeScript/JavaScript linting)
- ✅ YAML/JSON/TOML validation
- ✅ Large file prevention (10MB limit)
- ✅ Commit message linting (commitizen)

2.2 .gitignore Analysis

⚠️ Status: MINIMAL - Needs Enhancement

Current .gitignore (5 entries only):

.flashrank_cache*
podcasts/
.env
node_modules/
.ruff_cache/

Issues:

❌ Missing common Python cache patterns (__pycache__/, *.pyc, *.pyo)
❌ Missing test/coverage artifacts (.pytest_cache/, .coverage, htmlcov/)
❌ Missing build artifacts (dist/, build/, *.egg-info/)
❌ Missing environment variations (.env.local, .env.production, .env.*.local)
❌ Missing credentials/secrets patterns (*.key, *.pem, *.cert, credentials.json, secrets.*)
❌ Missing log files (*.log, logs/, .log/)
❌ Missing OS-specific files (.DS_Store, Thumbs.db)
❌ Missing IDE files (.idea/, *.swp, *.swo)
❌ Missing database files (*.db, *.sqlite, *.sqlite3)

Recommendation: Enhance .gitignore with comprehensive patterns (see Recommendations section).

2.3 Docker Security

✅ Status: GOOD with minor notes

Findings:

Multi-stage builds: Not used, but acceptable for this project size
Base image: python:3.12-slim (good - minimal attack surface)
Security updates: ✅ Includes apt-get update, certificate management
Non-root user: ❌ Runs as root (line 75: no USER directive)
Secrets handling: ✅ Uses .env files, not baked into image
SSL certificates: ✅ Properly configured with certifi

docker-compose.yml:

✅ Uses environment variable substitution
✅ Default credentials are weak (postgres:postgres) but documented for local dev
✅ Services properly isolated with Docker networks
✅ pgAdmin included for database management

Site Configuration System

Implementation Date: 2025-11-18 Implemented By: Claude AI Assistant (Anthropic Sonnet 4.5) Feature: Dynamic Site Appearance Configuration

Overview

The site configuration system provides administrators with a centralized, database-driven approach to control the visibility and behavior of homepage elements, navigation links, footer sections, and route availability. This eliminates hardcoded UI elements and enables runtime customization without code changes.

Architecture

Backend Stack:

Database: PostgreSQL singleton pattern (single row with id=1)
ORM: SQLAlchemy with AsyncSession
Migration: Alembic migration #38
API Framework: FastAPI with Pydantic validation
Access Control: Superuser-only admin endpoints, public read endpoint

Frontend Stack:

State Management: React Context API (SiteConfigContext)
UI Framework: Next.js 15.5.6 App Router
Conditional Rendering: Client-side based on configuration
Route Guards: RouteGuard component for disabled routes

Database Schema

Table: site_configuration (singleton - only 1 row)

CREATE TABLE site_configuration (
    id INTEGER PRIMARY KEY,  -- Always 1 (singleton)

    -- Header/Navbar toggles
    show_pricing_link BOOLEAN DEFAULT FALSE,
    show_docs_link BOOLEAN DEFAULT FALSE,
    show_github_link BOOLEAN DEFAULT FALSE,
    show_sign_in BOOLEAN DEFAULT TRUE,

    -- Homepage toggles
    show_get_started_button BOOLEAN DEFAULT FALSE,
    show_talk_to_us_button BOOLEAN DEFAULT FALSE,

    -- Footer toggles
    show_pages_section BOOLEAN DEFAULT FALSE,
    show_legal_section BOOLEAN DEFAULT FALSE,
    show_register_section BOOLEAN DEFAULT FALSE,

    -- Route disabling
    disable_pricing_route BOOLEAN DEFAULT TRUE,
    disable_docs_route BOOLEAN DEFAULT TRUE,
    disable_contact_route BOOLEAN DEFAULT TRUE,
    disable_terms_route BOOLEAN DEFAULT TRUE,
    disable_privacy_route BOOLEAN DEFAULT TRUE,

    -- Custom text
    custom_copyright VARCHAR(200) DEFAULT 'SurfSense 2025',

    CONSTRAINT check_singleton CHECK (id = 1)
);

Migration: surfsense_backend/alembic/versions/38_add_site_configuration_table.py

API Endpoints

1. Public Configuration (Unauthenticated)

GET /api/v1/site-config/public

Response:

{
  "show_pricing_link": false,
  "show_docs_link": false,
  "show_github_link": false,
  "show_sign_in": true,
  "show_get_started_button": false,
  "show_talk_to_us_button": false,
  "show_pages_section": false,
  "show_legal_section": false,
  "show_register_section": false,
  "disable_pricing_route": true,
  "disable_docs_route": true,
  "disable_contact_route": true,
  "disable_terms_route": true,
  "disable_privacy_route": true,
  "custom_copyright": "SurfSense 2025"
}

2. Admin Configuration (Superuser Only)

GET /api/v1/site-config
Authorization: Bearer <jwt_token>

Response: Same as public endpoint

3. Update Configuration (Superuser Only)

PUT /api/v1/site-config
Authorization: Bearer <jwt_token>
Content-Type: application/json

{
  "show_pricing_link": true,
  "custom_copyright": "© MyCompany 2025"
}

Response: Updated configuration object

Frontend Integration

1. Global Context

File: surfsense_web/contexts/SiteConfigContext.tsx

const { config, isLoading, error, refetch } = useSiteConfig();

// Access any configuration value
const showPricing = config.show_pricing_link;
const copyright = config.custom_copyright;

Initialization: Wrapped in app/layout.tsx for global availability

2. Conditional Rendering Examples

Navbar (components/homepage/navbar.tsx):

{config.show_pricing_link && !config.disable_pricing_route && (
  <Link href="/pricing">Pricing</Link>
)}

{config.show_github_link && (
  <Link href="https://github.com/okapteinis/SurfSense">
    <IconBrandGithub />
  </Link>
)}

Homepage Hero (components/homepage/hero-section.tsx):

{config.show_get_started_button && (
  <Link href="/register" className="btn-primary">
    Get Started
  </Link>
)}

Footer (components/homepage/footer.tsx):

<p>&copy; {config.custom_copyright || "SurfSense 2025"}</p>

{config.show_legal_section && (
  <div>
    {!config.disable_terms_route && <Link href="/terms">Terms</Link>}
    {!config.disable_privacy_route && <Link href="/privacy">Privacy</Link>}
  </div>
)}

3. Route Guarding

File: components/RouteGuard.tsx

<RouteGuard routeKey="pricing">
  <PricingPage />
</RouteGuard>

Protected Routes:

/pricing → checks disable_pricing_route
/contact → checks disable_contact_route
/terms → checks disable_terms_route
/privacy → checks disable_privacy_route

Behavior: Redirects to /404 if route is disabled

Admin Panel

Location: /dashboard/site-settings

Features:

✅ Visual toggle switches for all boolean flags
✅ Text input for custom copyright
✅ Real-time updates via API
✅ Organized by section (Header, Homepage, Footer, Routes, Custom Text)
✅ Descriptions for each toggle
✅ Save button with loading state
✅ Toast notifications for success/error

Access Control: Requires superuser authentication (JWT token)

UI Components:

Custom ToggleSwitch component with animated transitions
Gradient save button matching brand colors
Dark mode support
Responsive design (mobile-friendly)

Configuration Options

Toggle	Description	Default
`show_pricing_link`	Show pricing link in navbar	`false`
`show_docs_link`	Show docs link in navbar	`false`
`show_github_link`	Show GitHub icon in navbar	`false`
`show_sign_in`	Show sign in button	`true`

Homepage Buttons

Toggle	Description	Default
`show_get_started_button`	Show "Get Started" CTA button	`false`
`show_talk_to_us_button`	Show "Talk to Us" CTA button	`false`

Footer Sections

Toggle	Description	Default
`show_pages_section`	Show pages section (Pricing, Docs, Contact)	`false`
`show_legal_section`	Show legal section (Terms, Privacy)	`false`
`show_register_section`	Show register section (Sign Up, Sign In)	`false`

Route Disabling

Toggle	Description	Default
`disable_pricing_route`	Disable /pricing route (404)	`true`
`disable_docs_route`	Disable /docs route (404)	`true`
`disable_contact_route`	Disable /contact route (404)	`true`
`disable_terms_route`	Disable /terms route (404)	`true`
`disable_privacy_route`	Disable /privacy route (404)	`true`

Custom Text

Field	Description	Default
`custom_copyright`	Footer copyright text (max 200 chars)	`"SurfSense 2025"`

Security Considerations

Access Control:
- Admin endpoints require is_superuser = true
- Public endpoint is read-only and unauthenticated
- JWT token validation on all admin operations
Input Validation:
- Pydantic schemas enforce data types
- String length limits (copyright max 200 chars)
- Boolean validation for all toggles
Singleton Pattern:
- Database constraint ensures only 1 configuration row
- get_or_create_config() helper prevents missing config
- Atomic updates via SQLAlchemy transactions
Client-Side Security:
- Configuration fetched at app startup
- No sensitive data exposed (public-facing settings only)
- RouteGuard prevents access to disabled routes

Migration Guide

Step 1: Apply Database Migration

cd surfsense_backend
alembic upgrade head

This creates the site_configuration table and inserts the default row.

Step 2: Verify Configuration

# Check that singleton row exists
psql -d surfsense -c "SELECT * FROM site_configuration WHERE id = 1;"

Step 3: Access Admin Panel

Log in as superuser
Navigate to /dashboard/site-settings
Configure toggles as desired
Click "Save Configuration"

Step 4: Verify Frontend Changes

Visit homepage at /
Check navbar for conditional links
Check footer for conditional sections
Test disabled routes (should show 404)

Testing Checklist

Database migration runs successfully
Singleton row created with default values
Public API endpoint returns configuration (unauthenticated)
Admin GET endpoint requires authentication
Admin PUT endpoint requires superuser role
Frontend context loads configuration on app startup
Navbar shows/hides links based on config
Homepage shows/hides buttons based on config
Footer shows/hides sections based on config
Custom copyright displays correctly
RouteGuard redirects disabled routes to 404
Admin panel UI loads and displays current config
Admin panel saves changes successfully
Changes reflect immediately after save (via refetch)

Google OAuth Removal for User Authentication

Implementation Date: 2025-11-18 Implemented By: Claude AI Assistant (Anthropic Sonnet 4.5) Feature: Email/Password-Only Authentication

Overview

Removed Google OAuth as an authentication method for user accounts, enforcing email/password authentication only. Google OAuth credentials are now exclusively used for Gmail and Google Calendar connector integrations, not for user sign-in/registration.

Changes Implemented

Backend Configuration

File: surfsense_backend/.env.example

Changed AUTH_TYPE from GOOGLE or LOCAL to LOCAL (email/password only)
Updated Google OAuth credentials documentation to clarify they're only for Gmail/Calendar connectors
Removed misleading "For Google Auth Only" comment

Before:

AUTH_TYPE=GOOGLE or LOCAL
# For Google Auth Only
GOOGLE_OAUTH_CLIENT_ID=924507538m
GOOGLE_OAUTH_CLIENT_SECRET=GOCSV

After:

AUTH_TYPE=LOCAL
# Google OAuth Credentials (OPTIONAL - Required only for Gmail and Google Calendar connectors)
GOOGLE_OAUTH_CLIENT_ID=your_google_client_id
GOOGLE_OAUTH_CLIENT_SECRET=your_google_client_secret

Frontend Configuration

File: surfsense_web/.env.example

Updated NEXT_PUBLIC_FASTAPI_BACKEND_AUTH_TYPE to LOCAL only
Removed or GOOGLE option

Frontend Components

File: surfsense_web/app/(home)/login/LocalLoginForm.tsx

Changes:

Removed authType state variable (line 27)
Removed useEffect that checked NEXT_PUBLIC_FASTAPI_BACKEND_AUTH_TYPE environment variable (lines 31-34)
Removed conditional check for showing registration link (line 236)
Now always displays "Don't have an account? Sign up" link

Rationale: Since authentication is email/password only, the registration link should always be visible. The authType check was unnecessary.

Documentation Updates

File: surfsense_web/content/docs/index.mdx

Changes:

Updated Auth Setup section to state "SurfSense uses email/password authentication for user accounts"
Removed references to deleted Google OAuth setup images (google_oauth_people_api.png, google_oauth_screen.png, google_oauth_client.png, google_oauth_config.png)
Clarified Google OAuth is only for Gmail/Calendar connectors
Added redirect URI examples for connector setup

Before:

## Auth Setup
SurfSense supports both Google OAuth and local email/password authentication...
![Google Developer Console People API](/docs/google_oauth_people_api.png)

After:

## Auth Setup
SurfSense uses email/password authentication for user accounts.

### Google OAuth for Connectors (Optional)
**Note**: Google OAuth setup is **required** only if you want to use the Gmail and Google Calendar connectors...

What Was NOT Changed

The following components were intentionally preserved:

OAuth Error Handling (surfsense_web/lib/auth-errors.ts):
- Generic OAuth error codes (lines 65-93) remain because they're needed for connector OAuth flows
- Error handling applies to any OAuth integration, not just user authentication
Backend OAuth Configuration (surfsense_backend/app/config/__init__.py):
- GOOGLE_OAUTH_CLIENT_ID and GOOGLE_OAUTH_CLIENT_SECRET environment variables still loaded
- Still used by google_gmail_add_connector_route.py and google_calendar_add_connector_route.py
Backend User Authentication Logic (surfsense_backend/app/users.py, app/app.py, app/db.py):
- Conditional logic checking AUTH_TYPE == "GOOGLE" remains
- Allows future re-enabling of Google OAuth if needed
- No breaking changes to existing authentication flow when AUTH_TYPE=LOCAL
Connector Integration:
- Google Calendar connector (app/dashboard/[search_space_id]/connectors/add/google-calendar-connector/page.tsx)
- Google Gmail connector (app/dashboard/[search_space_id]/connectors/add/google-gmail-connector/page.tsx)
- Both still use Google OAuth for accessing user's Google data

Deployment Steps Completed

✅ Updated local repository to latest nightly branch
✅ Identified and analyzed all OAuth references in codebase
✅ Removed authType state check from LocalLoginForm
✅ Updated .env.example files (frontend and backend)
✅ Fixed documentation to remove deleted OAuth images
✅ Committed changes with descriptive messages:
- Commit 1 (586ab48): "Remove Google OAuth from login/register, enforce email-only authentication"
- Commit 2 (a148614): "Fix documentation: Remove deleted Google OAuth images, clarify auth is email-only"
✅ Pushed changes to nightly branch
✅ Deployed to VPS at 46.62.230.195
✅ Rebuilt frontend on VPS (pnpm build)
✅ Restarted all services:
- surfsense.service (Backend)
- surfsense-frontend.service (Frontend)
- surfsense-celery.service (Worker)
- surfsense-celery-beat.service (Scheduler)
✅ Verified deployment at https://ai.kapteinis.lv/login and https://ai.kapteinis.lv/register

Verification Results

Login Page (https://ai.kapteinis.lv/login):

✅ Email and password fields present
✅ "Don't have an account? Sign up" link visible
✅ No Google OAuth or "Continue with Google" button
✅ Page loads correctly without errors
✅ Only email/password authentication available

Register Page (https://ai.kapteinis.lv/register):

✅ Email, password, and confirm password fields present
✅ No Google OAuth references
✅ "Already have an account? Sign In" link visible
✅ Page loads successfully

Files Modified

Backend:

surfsense_backend/.env.example                    # AUTH_TYPE=LOCAL, clarified OAuth usage

Frontend:

surfsense_web/.env.example                        # AUTH_TYPE=LOCAL
surfsense_web/app/(home)/login/LocalLoginForm.tsx # Removed authType check
surfsense_web/content/docs/index.mdx              # Updated auth documentation

Benefits

Simplified Authentication: Users no longer confused by multiple auth methods
Reduced Dependencies: No dependency on Google OAuth service for user authentication
Privacy-Focused: User accounts managed entirely within SurfSense
Clear Documentation: Distinction between user auth and connector OAuth
Maintained Functionality: Gmail/Calendar connectors still work with OAuth

Future Considerations

If Google OAuth needs to be re-enabled for user authentication:

Set AUTH_TYPE=GOOGLE in backend .env
Set NEXT_PUBLIC_FASTAPI_BACKEND_AUTH_TYPE=GOOGLE in frontend .env
Provide valid GOOGLE_OAUTH_CLIENT_ID and GOOGLE_OAUTH_CLIENT_SECRET
Backend conditional logic will automatically enable Google OAuth routes

The backend code architecture supports both authentication methods through configuration, making this a non-breaking change.

Testing Checklist

Login page shows only email/password fields
Register page shows only email/password fields
"Don't have an account?" link always visible on login
"Already have an account?" link visible on register
No Google OAuth button or references in UI
Documentation updated to reflect email-only auth
.env.example files updated
Frontend builds successfully
Services restart without errors
Login page loads at https://ai.kapteinis.lv/login
Register page loads at https://ai.kapteinis.lv/register
Gmail connector OAuth still functional (preserved)
Calendar connector OAuth still functional (preserved)

Support

For questions or issues related to authentication:

Review backend users configuration: surfsense_backend/app/users.py
Check authentication routes: surfsense_backend/app/app.py
Examine frontend login form: surfsense_web/app/(home)/login/LocalLoginForm.tsx
Verify environment variables in .env files

Registration Toggle System

Implementation Date: 2025-11-18 Implemented By: Claude AI Assistant (Anthropic Sonnet 4.5) Feature: Disable User Registration via Admin Panel

Overview

Implemented a comprehensive registration control system that allows administrators to disable new user registrations through the admin panel. This provides better control over user access and supports closed registration scenarios for private deployments.

Implementation Summary

The registration toggle system operates at multiple layers:

Database Layer: Added disable_registration boolean field to site_configuration table (migration #39)
Backend API Layer: Updated registration_allowed() dependency to check database toggle and return 403 when disabled
Frontend UI Layer: Conditionally hide "Sign Up" link on login page based on configuration
Frontend Route Layer: RouteGuard component protects /register route, showing 404 when disabled
Admin Panel Layer: Added "Registration Control" section to site-settings page for easy toggling

Backend Changes

Database Migration (#39)

File: surfsense_backend/alembic/versions/39_add_disable_registration_to_site_configuration.py

def upgrade() -> None:
    op.add_column(
        'site_configuration',
        sa.Column('disable_registration', sa.Boolean(), nullable=False, server_default='false')
    )

def downgrade() -> None:
    op.drop_column('site_configuration', 'disable_registration')

Revision ID: '39' (shortened to fit varchar(32) constraint) Down Revision: '38_add_site_configuration_table' Default Value: false (registration enabled by default)

Database Model

File: surfsense_backend/app/db.py

class SiteConfiguration(SQLModel, table=True):
    # ... existing fields ...

    # Registration control
    disable_registration = Column(Boolean, nullable=False, default=False)

API Schemas

File: surfsense_backend/app/schemas/site_configuration.py

class SiteConfigurationBase(BaseModel):
    # ... existing fields ...

    # Registration control
    disable_registration: bool = False

class SiteConfigurationUpdate(SiteConfigurationBase):
    # ... existing fields ...
    disable_registration: bool | None = None

Registration Endpoint Protection

File: surfsense_backend/app/app.py

async def registration_allowed(session: AsyncSession = Depends(get_async_session)):
    # Check environment variable first
    if not config.REGISTRATION_ENABLED:
        raise HTTPException(
            status_code=status.HTTP_403_FORBIDDEN,
            detail="Registration is disabled by system configuration"
        )

    # Check site configuration database toggle
    result = await session.execute(select(SiteConfiguration).where(SiteConfiguration.id == 1))
    site_config = result.scalar_one_or_none()

    if site_config and site_config.disable_registration:
        raise HTTPException(
            status_code=status.HTTP_403_FORBIDDEN,
            detail="Registration is currently disabled. Please contact the administrator if you need access."
        )

    return True

# Applied to registration routes
app.include_router(
    fastapi_users.get_register_router(UserRead, UserCreate),
    prefix="/auth",
    tags=["auth"],
    dependencies=[Depends(registration_allowed)],  # Enforces registration check
)

Error Response (when disabled):

{
  "detail": "Registration is currently disabled. Please contact the administrator if you need access."
}

Route Guard

File: surfsense_web/components/RouteGuard.tsx

Changes:

Extended routeKey type to include "registration"
Added special case handling for registration toggle

interface RouteGuardProps {
    children: React.ReactNode;
    routeKey: "pricing" | "docs" | "contact" | "terms" | "privacy" | "registration";
}

export function RouteGuard({ children, routeKey }: RouteGuardProps) {
    const { config, isLoading } = useSiteConfig();
    const router = useRouter();

    // Special case: registration uses disable_registration instead of disable_registration_route
    const disableKey = routeKey === "registration"
        ? "disable_registration"
        : (`disable_${routeKey}_route` as keyof typeof config);
    const isDisabled = config[disableKey as keyof typeof config];

    if (isDisabled) {
        router.replace("/404");
        return null;
    }

    return <>{children}</>;
}

Register Page

File: surfsense_web/app/(home)/register/page.tsx

Changes:

Imported RouteGuard component
Wrapped entire page content with <RouteGuard routeKey="registration">

import { RouteGuard } from "@/components/RouteGuard";

export default function RegisterPage() {
    return (
        <RouteGuard routeKey="registration">
            {/* ... registration form content ... */}
        </RouteGuard>
    );
}

Behavior: When disable_registration is true, accessing /register redirects to /404

Admin Panel

File: surfsense_web/app/dashboard/site-settings/page.tsx

Changes:

Added disable_registration: boolean to SiteConfigForm interface
Added default value disable_registration: false to form state
Added field to useEffect that loads config from API
Added new "Registration Control" section in UI

interface SiteConfigForm {
    // ... existing fields ...
    disable_registration: boolean;
}

{/* Registration Control Section */}
<section>
    <h2 className="text-xl font-semibold text-gray-900 dark:text-white mb-4">
        Registration Control
    </h2>
    <p className="text-sm text-gray-600 dark:text-gray-400 mb-4">
        Control user registration availability. When disabled, the Sign Up link will be hidden
        and the registration page will show a 404 error. The backend will also block registration
        requests with a 403 error.
    </p>
    <div className="space-y-3">
        <ToggleSwitch
            label="Disable Registration"
            description="Prevent new users from creating accounts"
            checked={formData.disable_registration}
            onChange={() => handleToggle("disable_registration")}
        />
    </div>
</section>

Behavior Summary

When Registration is ENABLED (default: `disable_registration = false`):

Login Page (/login):
- Shows "Don't have an account? Sign up" link
- Link navigates to /register
Register Page (/register):
- Page loads normally
- Registration form accepts submissions
- Backend POST /auth/register succeeds (200)
Admin Panel (/dashboard/site-settings):
- "Disable Registration" toggle is OFF
- Description explains what happens when enabled

When Registration is DISABLED (`disable_registration = true`):

Login Page (/login):
- "Don't have an account? Sign up" link is HIDDEN
- No visual indication of registration functionality
Register Page (/register):
- RouteGuard redirects to /404 (route disabled)
- Page shows standard 404 error
Backend API (POST /auth/register):
- Returns 403 Forbidden
- Error message: "Registration is currently disabled. Please contact the administrator if you need access."
Admin Panel (/dashboard/site-settings):
- "Disable Registration" toggle is ON (orange)
- Admins can toggle back to enable registration

Security Considerations

Layered Protection:
- Frontend hides UI elements (Sign Up link)
- Frontend route guard blocks page access
- Backend API validates and blocks requests
- Defense in depth approach prevents bypass attempts
Database-Driven:
- Configuration stored in PostgreSQL (singleton row with id=1)
- Atomic updates via SQLAlchemy transactions
- Consistent state across all application instances
Admin-Only Access:
- Only superusers can access /dashboard/site-settings
- JWT authentication required for PUT /api/v1/site-config
- Public GET /api/v1/site-config/public is read-only
Graceful Error Messages:
- User-friendly 403 message explains registration is disabled
- Directs users to contact administrator
- No technical details exposed

Deployment Steps

✅ Pull latest code: git pull origin nightly
✅ Apply migration: alembic upgrade head (migration #39)
✅ Rebuild frontend: pnpm build
✅ Restart services: systemctl restart surfsense.service surfsense-frontend.service surfsense-celery.service surfsense-celery-beat.service
✅ Verify deployment: All services active

Deployment Date: 2025-11-18 Deployment Location: https://ai.kapteinis.lv VPS: 46.62.230.195

Migration Notes

Issue Encountered: Revision ID Too Long

Problem: Alembic alembic_version table has varchar(32) constraint on version_num column. Original revision ID '39_add_disable_registration_to_site_configuration' (50 characters) exceeded limit.

Error:

sqlalchemy.exc.DBAPIError: <class 'asyncpg.exceptions.StringDataRightTruncationError'>:
value too long for type character varying(32)
[SQL: UPDATE alembic_version SET version_num='39_add_disable_registration_to_site_configuration'
WHERE alembic_version.version_num = '38_add_site_configuration_table']

Solution: Shortened revision ID using sed on VPS:

sed -i "s/revision: str = '39_add_disable_registration_to_site_configuration'/revision: str = '39'/g" \
    alembic/versions/39_add_disable_registration_to_site_configuration.py

Final Revision ID: '39' (2 characters, fits varchar(32))

Note: Migration #38 uses long ID '38_add_site_configuration_table' but succeeded before (possibly database was modified to allow longer IDs, or varchar constraint was later added).

Testing Checklist

Default State (Registration Enabled):

Login page shows "Sign up" link
/register page loads successfully

Commit Information

Commit Hash: b8bb74e Branch: nightly Message:

Add disable_registration toggle to site configuration

Implemented comprehensive registration control system that allows administrators
to disable new user registrations through the admin panel. This provides better
control over user access and supports closed registration scenarios.

Backend changes:
- Added disable_registration field to SiteConfiguration model (db.py)
- Created migration #39 to add disable_registration column with default false
- Updated SiteConfigurationBase, Update, and Read schemas
- Enhanced registration_allowed() dependency to check database toggle
- Returns 403 with clear message when registration is disabled

Frontend changes:
- Added disable_registration to SiteConfig interface and default config
- Updated LocalLoginForm to conditionally hide "Sign up" link when disabled
- Added RouteGuard support for "registration" route key
- Protected /register page with RouteGuard (shows 404 when disabled)
- Added "Registration Control" section to admin site-settings page

Use Cases

Private Deployments:
- Organization wants to control who can create accounts
- Only invite approved users, disable public registration
- Admin manually creates accounts for new employees
Capacity Management:
- Server approaching resource limits
- Temporarily disable registration until scaling completed
- Re-enable when infrastructure ready
Closed Beta:
- Limited initial user base for testing
- Disable registration after target number reached
- Re-enable for public launch
Security Incident Response:
- Spam/abuse accounts being created
- Quickly disable registration to stop attack
- Investigate and re-enable when resolved

Troubleshooting

Issue: Toggle doesn't save in admin panel

Symptoms: Clicking toggle works, but changes don't persist after refresh

Diagnosis:

Check browser console for API errors
Verify JWT token is valid (localStorage.getItem('access_token'))
Check backend logs for 401/403 errors
Confirm user is superuser (is_superuser = true)

Solution: Ensure logged-in user has superuser privileges

Symptoms: Login page shows Sign Up link despite toggle being ON

Diagnosis:

Check if frontend context refetched after save
Inspect SiteConfigContext state in React DevTools
Verify GET /api/v1/site-config/public returns disable_registration: true

Solution: Hard refresh browser (Ctrl+Shift+R) or wait for automatic refetch

Issue: /register page still loads instead of 404

Symptoms: Accessing /register shows form instead of 404 error

Diagnosis:

Verify RouteGuard is wrapping RegisterPage component
Check SiteConfigContext has correct disable_registration value
Confirm RouteGuard logic handles "registration" route key

Solution: Verify frontend build includes latest changes, restart frontend service

Issue: Backend still accepts registrations despite toggle

Symptoms: POST /auth/register returns 200 instead of 403

Diagnosis:

Check database: SELECT disable_registration FROM site_configuration WHERE id = 1;
Verify registration_allowed() function checks database
Confirm dependency is applied to register router

Solution: Restart backend service to reload code changes

Future Enhancements

Potential additions (not yet implemented):

Registration whitelist (allow specific email domains)
Invitation-based registration (one-time tokens)
