## Bot detection

Sensitive API endpoints are protected by bot detection to prevent automated abuse. Protected endpoints return a `403` status code when a request is identified as coming from an automated source.

**Protected endpoints:**

| Endpoint | Purpose |
|----------|---------|
| `/api/register` | Prevents fake account creation |
| `/api/auth/forgot-password` | Blocks automated password reset abuse |

Requests from standard web browsers are not affected. Automated clients such as scripts or bots may be blocked. If you are building a legitimate integration and receive a `403` response, ensure your requests originate from an environment that supports browser-level verification.

## Trust Principles

### 1. Minimal Data Collection
- We don't store prompts or generated images permanently
- Demo skills use in-memory data that resets on restart
- No user data sent to third parties (except Replicate for image generation)

### 2. Input Sanitization
All user inputs are:
- Length-limited (max 100-500 chars depending on field)
- Type-checked (strings, arrays, numbers)
- Allowlist-validated (enum values must match predefined lists)
- HTML/JS stripped (`<>` characters removed)

### 3. API Key Security
- Replicate API tokens stored in server-side environment variables
- Never exposed to client-side code
- Used only for image generation requests

### 4. Read-Only Skills
Track Archaeologist, Setlist Oracle, Royalty Tracker, Venue Finder, Festival Finder, and Event Scheduler are **read-only**:
- No user data stored
- No external API calls
- Uses only in-memory mock catalog
- Safe for public demo use

## Row-level security

All user-scoped database tables are protected by PostgreSQL row-level security (RLS) policies. Each authenticated request sets a user context at the database level before any query executes, so users can only read and modify their own data.

### Protected tables

| Table | Policy | Isolation key |
|-------|--------|---------------|
| `User` | `user_isolation` | `id` |
| `Agent` | `agent_isolation` | `userId` |
| `ScheduledTask` | `task_isolation` | `userId` |
| `AgentMemory` | `memory_isolation` | `userId` |
| `AgentFile` | `file_isolation` | `userId` |
| `InstalledSkill` | `skill_isolation` | `userId` |
| `AgentSwarm` | `swarm_isolation` | `userId` |
| `Workflow` | `workflow_isolation` | `userId` |
| `Wallet` | `wallet_isolation` | `userId` |
| `ApiKey` | `apikey_isolation` | `userId` |
| `Account` | `account_isolation` | `userId` |
| `Session` | `session_isolation` | `userId` |

### Admin bypass

Users with the `admin` role bypass RLS policies and can access all rows across tenants. Admin access is determined by the `role` column on the `User` table.

### How it works

1. The auth middleware verifies the JWT and extracts the `userId`.
2. Before any database query, the middleware calls `set_current_user_id(userId)` to set a PostgreSQL session variable.
3. RLS policies on each table compare the row's `userId` (or `id` for the `User` table) against the session variable.
4. Queries automatically return only rows belonging to the authenticated user.

<Note>RLS is enforced at the database level and cannot be bypassed by application code. Even if a query omits a `WHERE` clause, only the authenticated user's rows are returned.</Note>

## Auth middleware

The backend API uses auth middleware that runs before protected endpoints. API key comparison uses `crypto.timingSafeEqual` to prevent timing-based key enumeration. Two middleware functions are available: the inline `authenticate` function on the main router, and a standalone [`requireAuth`](/api-reference/auth#standalone-auth-middleware-requireauth) middleware that can be applied to individual route handlers not mounted through the main router.

### Authentication flow

1. The client includes a `Bearer` token in the `Authorization` header.
2. The middleware performs a constant-time comparison of the token against the server key.
3. On success, the middleware attaches `userId`, `userEmail`, and `userRole` to the request and sets the RLS context.
4. On failure, the endpoint returns one of the error codes below.

### HMAC signature verification

The backend `authenticate` middleware verifies user context headers using HMAC-SHA256 signatures. When the frontend proxy forwards requests to the backend, it signs the user context (`userId:userEmail:userRole`) with a shared secret and includes the signature in the `x-user-signature` header. The backend verifies this signature before trusting the forwarded user identity.

The signing secret is read from `HMAC_SECRET`, falling back to `INTERNAL_API_KEY`. When the secret is configured, all requests with user context headers must include a valid signature. See the [API reference](/api-reference/auth#header-based-authentication-backend-user-context) for header details and error codes.

### Error codes

| Code | HTTP status | Description |
|------|-------------|-------------|
| `AUTH_REQUIRED` | 401 | No `Authorization` header or missing `Bearer` prefix |
| `TOKEN_INVALID` | 401 | JWT signature verification failed or token has expired |
| `SIGNATURE_REQUIRED` | 401 | HMAC secret is configured but no `x-user-signature` header was provided |
| `INVALID_SIGNATURE` | 401 | The HMAC-SHA256 signature does not match the expected value |
| `AUTH_ERROR` | 500 | Unexpected error during authentication |
| `ADMIN_REQUIRED` | 403 | Endpoint requires admin privileges and the authenticated user is not an admin |

### Admin endpoints

Endpoints that require admin access use an additional `requireAdmin` check after authentication. The admin check compares the authenticated user's email against the `ADMIN_EMAILS` environment variable using a **case-insensitive** match. Non-admin users receive a `403` response with code `ADMIN_REQUIRED`.

## Header stripping

Both the backend API and the web frontend strip or reject requests that include headers commonly used to bypass URL-based access controls. The following headers are removed from every inbound request before it reaches any route handler:

| Header | Reason |
|--------|--------|
| `X-Original-URL` | Prevents IIS/reverse-proxy URL override attacks |
| `X-Rewrite-URL` | Prevents IIS/reverse-proxy URL rewrite attacks |
| `X-Forwarded-Host` | Prevents host header injection and routing manipulation |

On the backend API, these headers are deleted in a global middleware that runs before all routes. On the web frontend, `X-Original-URL` and `X-Rewrite-URL` are additionally scanned for injection patterns and the request is rejected with a `400` status if a suspicious payload is detected.

<Note>If your reverse proxy or CDN injects any of these headers, they will be silently removed. Do not rely on them for application logic.</Note>

## Web API security middleware

The web frontend wraps API routes with security middleware that provides:

- **Rate limiting** — per-IP request limits
- **DDoS protection** — automated request filtering
- **Bot detection** — blocks automated abuse on sensitive endpoints
- **SQL injection prevention** — request parameters and body are scanned for injection patterns
- **XSS prevention** — payloads containing script tags or event handlers are rejected
- **JSON validation** — `Content-Type` enforcement and body parsing on mutation endpoints
- **CSRF protection** — token-based verification using the `x-csrf-token` or `x-xsrf-token` header, enforced on the login endpoint and all sensitive mutation routes
- **Header stripping** — bypass headers (`X-Original-URL`, `X-Rewrite-URL`, `X-Forwarded-Host`) are removed or rejected

### Route protection levels

| Level | Wrapper | Includes |
|-------|---------|----------|
| Public | `SecureRoute.public` | Rate limiting, bot detection, input validation |
| Protected | `SecureRoute.protected` | Public checks + session or API key authentication |
| Mutation | `SecureRoute.mutation` | Protected checks + POST-only enforcement |
| JSON | `SecureRoute.json` | Public checks + POST-only + JSON content-type validation |
| Sensitive | `SecureRoute.sensitive` | Protected + POST-only + JSON validation + CSRF token |

### Error codes

| HTTP status | Description |
|-------------|-------------|
| 400 | Invalid JSON body, missing `Content-Type: application/json`, or injection pattern detected in request |
| 401 | Missing authentication credentials |
| 403 | Invalid or missing CSRF token |
| 405 | HTTP method not allowed (non-POST request on a mutation endpoint) |
| 429 | Too many failed authentication attempts from the same IP |

## SSRF protection

Webhook URLs are validated before any outbound request is made. URLs that resolve to private or internal IP ranges are rejected, including:

- `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`
- `127.0.0.0/8` (localhost) and `::1`
- Link-local and other reserved ranges

This prevents server-side request forgery (SSRF) attacks where an attacker could use webhook configuration to probe internal services.

## Agent-to-agent authentication

All agent-to-agent (A2A) messages are verified before delivery. The `verifyMessage()` check runs before `deliverMessage()`, ensuring that unauthenticated A2A messages are blocked. Additionally, negotiation actions (accepting or declining bookings) enforce ownership checks — only the originating agent can modify its own bookings.

## CORS

The backend API restricts CORS to an explicit allowlist. The `ALLOWED_ORIGINS` environment variable accepts a comma-separated list of permitted origins. When unset, the API defaults to a built-in allowlist rather than accepting all origins. Wildcard (`*`) origins are not supported. Requests from unlisted origins receive a CORS error. Credentials are supported.

The `X-Powered-By` header is disabled on both the API (Express) and the web frontend (Next.js) to reduce fingerprinting surface.

## HTTP security headers

All web frontend responses include the following security headers:

| Header | Value | Purpose |
|--------|-------|---------|
| `Content-Security-Policy` | Restrictive policy with `default-src 'self'`, `base-uri 'self'`, `object-src 'none'`, `form-action 'self'`, and `upgrade-insecure-requests` | Limits sources for scripts, styles, images, and connections. Restricts `<base>` tags and form targets to same-origin, blocks plugin content, and forces HTTPS for subresource requests. |
| `X-Frame-Options` | `DENY` | Prevents clickjacking by blocking iframe embedding |
| `X-Content-Type-Options` | `nosniff` | Prevents MIME type sniffing |
| `Referrer-Policy` | `strict-origin-when-cross-origin` | Limits referrer information sent to external sites |
| `Permissions-Policy` | `camera=(), microphone=(), geolocation=()` | Disables access to sensitive browser APIs |
| `Cross-Origin-Opener-Policy` | `same-origin-allow-popups` | Isolates browsing context from cross-origin windows |
| `Strict-Transport-Security` | `max-age=63072000; includeSubDomains; preload` | Enforces HTTPS for two years, including all subdomains |

### Cache control

API responses include `no-cache, no-store, must-revalidate` to prevent caching of sensitive data. Static assets under `/public`, `/_next`, and `/assets` use `public, max-age=31536000, immutable` for long-term caching.

## Known limitations

### Demo mode
Currently skills run in demo mode. In production:
- API rate limits will be per-user

### In-memory storage

Groupie Manager uses in-memory Map storage. Data is:
- Lost on server restart
- Not shared between server instances
- Only for demonstration purposes

### In-memory rate limiting (cold starts)

The web API security middleware uses in-memory stores for rate limiting, failed auth tracking, and bot detection. On serverless platforms (such as Vercel), this state resets on every cold start. For persistent rate limiting in production, configure `KV_REST_API_URL` and `KV_REST_API_TOKEN` to use Redis-backed storage. Without Redis, rate limits may be temporarily bypassed after a cold start until the in-memory counters rebuild.

Social post rate limiting and duplicate detection always use Upstash KV (via `KV_REST_API_URL` / `KV_REST_API_TOKEN`) and are not affected by cold starts. See [Social post rate limits](/api-reference/overview#social-post-rate-limits) for the per-agent daily limits.

## Google RISC Protocol

Agentbot implements Google's [RISC (Risk Incident Sharing and Collaboration)](https://developers.google.com/identity/protocols/risc) protocol for enhanced OAuth security. Two endpoints handle RISC events, each serving a different role.

### What is RISC?

RISC enables real-time security event sharing between Google and Agentbot. When Google detects a security incident (compromised account, suspicious activity, etc.), it sends a webhook to Agentbot to take immediate action.

### Endpoints

| Endpoint | Purpose |
|----------|---------|
| `POST /api/security/risc` | Cross-Account Protection receiver with token validation, event deduplication, and hijacking-specific responses |
| `POST /api/auth/google/risc` | Legacy RISC webhook that revokes sessions on security events |

The `/api/security/risc` endpoint is the primary receiver for Google Cross-Account Protection. It validates the SET (Security Event Token) JWT against Google's signing keys, checks the issuer and audience claims, deduplicates events using the `jti` claim, and takes targeted action depending on the event type. See the [API reference](/api-reference/auth#cross-account-protection-receiver) for full details.

### Supported events

| Event | `/api/security/risc` action | `/api/auth/google/risc` action |
|-------|----------------------------|-------------------------------|
| `account-disabled` (hijacking) | Disables Google Sign-in and invalidates all sessions | Revokes all sessions |
| `account-disabled` (other) | Invalidates all sessions | Revokes all sessions |
| `account-enabled` | Re-enables Google Sign-in | No action taken |
| `sessions-revoked` | Invalidates all sessions | Revokes all sessions |
| `tokens-revoked` | Revokes stored OAuth tokens and invalidates sessions | Not handled |
| `account-credential-change-required` | Logged for monitoring | Not handled |
| `verification` | Acknowledged (used during setup) | Not handled |
| `account-compromised` | Not handled | Revokes all sessions |
| `identifier-changed` | Not handled | Revokes all sessions |

<Note>The `/api/security/risc` endpoint matches users by Google subject ID (`sub`) or email address. The `/api/auth/google/risc` endpoint matches by email only.</Note>

### Event deduplication

The `/api/security/risc` endpoint deduplicates events using the `jti` (JWT ID) claim. Each event is stored in the `risc_events` table with a unique constraint on the `jti` column. Duplicate events are acknowledged but not processed again.

### Token validation

The `/api/security/risc` endpoint validates incoming SET JWTs by:

1. Verifying the issuer is `https://accounts.google.com/`
2. Checking the audience matches a configured `GOOGLE_CLIENT_ID`
3. Fetching Google's RISC signing keys from the JWKS endpoint discovered via `https://accounts.google.com/.well-known/risc-configuration` (keys are cached for 24 hours)
4. Matching the signing key by `kid` header claim
5. Verifying the RS256 signature using the Web Crypto API (`crypto.subtle`) with the matched RSA public key

### Security response

When a RISC event is received:

1. **Immediate**: Disable Google Sign-in (for hijacking events) or invalidate sessions
2. **Audit**: Log event type and affected user for security review
3. **Recovery**: User must re-authenticate on next visit

### Configuration

RISC events are configured in Google Cloud Console:

1. Go to **APIs & Services** → **Google RISC API**
2. Add the webhook URL: `https://agentbot.sh/api/security/risc`
3. Configure event types to receive
4. Set delivery method (push or poll)

The endpoint requires the `GOOGLE_CLIENT_ID` environment variable. Multiple client IDs can be provided as a comma-separated list.
