Code Review PR 2043 - Spatialwalk Avatar Example AgentThank you for this substantial contribution adding 21,505 lines across 148 files. I conducted a thorough review focusing on code quality, security, performance, and best practices. Critical Issues - Must Fix Before Merge1. Hardcoded API Credentials in Version Control - HIGH SEVERITYLocation: ai_agents/agents/examples/spatialwalk-avatar/frontend/.env The .env file contains a hardcoded Spatialwalk App ID being committed to the repository. Required Fix:
2. Missing Input Validation in API Route - HIGH SEVERITYLocation: frontend/src/app/api/agents/start/route.tsx:54 The API route forwards user input directly to backend without validation. Risks:
Recommended: Add validation for request_id, channel_name, user_uid, graph_name, and properties fields with type checking and regex patterns. 3. Improper Error Handling Exposes System DetailsLocation: frontend/src/app/api/agents/start/route.tsx:54 Issues:
Recommended: Use proper error responses with appropriate status codes. High Priority Issues4. Type Safety - Excessive Use of anyMultiple files in frontend/src/common/ use liberal any types defeating TypeScript type checking. 5. Potential Memory Leak in Avatar ComponentLocation: frontend/src/components/Agent/AvatarSpatialwalk.tsx:231 Cleanup code has race conditions using void on cleanup promises and calling dispose before async cleanup completes. 6. Insecure Random ID GenerationLocation: frontend/src/common/utils.ts:103 Issues:
Risk: User ID collisions, potential session hijacking 7. Missing CSRF ProtectionNo CSRF tokens or SameSite cookie protection visible in API routes. Performance Concerns8. Inefficient Audio Processing LoopLocation: frontend/src/common/hooks.ts:227 Audio visualizer updates 100 times per second regardless of changes. 9. Polling in Avatar InitializationBusy-waiting loop checking container dimensions. Code Quality Issues10. Missing Dependency Arrays in CallbacksLocation: frontend/src/app/page.tsx:96 Stale closure issue - callback wont have latest state. 11. Inconsistent Error HandlingFunctions throw strings, Errors, or return error objects inconsistently. Test Coverage - HIGH PRIORITY12. Minimal Test CoverageThe PR adds substantial functionality but includes minimal test coverage:
Recommendation: Add comprehensive test coverage before merging targeting at least 60 percent for critical paths. Docker and Infrastructure13. Docker Security Best PracticesLocation: Dockerfile:83 Issues:

Code Review: PR #2043 - Spatialwalk Avatar ExampleThank you for this substantial contribution! I've reviewed the 21,421 line addition and found good architectural patterns but several critical security concerns that need addressing. 🔴 CRITICAL Security Issues1. Unvalidated URL Opening (XSS/Phishing Risk)Location: frontend/src/manager/rtc/rtc.ts:271-275 Opens arbitrary URLs without validation. Agent responses could redirect users to malicious sites. Recommendation: Validate URLs with strict whitelist using URL() constructor. 2. Unprotected JSON.parse OperationsLocation: frontend/src/manager/rtc/rtc.ts:241, 256 No try-catch or schema validation. Malformed JSON causes crashes. Recommendation: Use zod for schema validation with proper error handling. 3. XSS Risk in Image URLsLocation: frontend/src/components/Chat/MessageList.tsx:63 Image src attributes populated directly from untrusted data. Accepts data: URIs, javascript: protocol, or SVG with embedded scripts. Recommendation: Validate image URLs, restrict to http/https protocols only. 4. Missing API Input ValidationLocation: frontend/src/app/api/agents/start/route.tsx:19-28 Request body forwarded to backend with no validation. Recommendation: Add zod schema validation for all API inputs (request_id, channel_name, user_uid, etc). 5. Exposed Spatialwalk App IDLocation: frontend/.env:5 NEXT_PUBLIC_SPATIALWALK_APP_ID committed to version control, exposing to all users. Could enable quota exhaustion. Recommendation: Move to server-side environment variable. 6. Weak Random ID GenerationLocation: frontend/src/common/utils.ts:17-23 Uses Math.random() with only 5-digit entropy (100000-199999 range). Could enable session hijacking. Recommendation: Use crypto.getRandomValues() for security-sensitive IDs.

Code Review: spatialwalk-avatar ExampleThank you for this comprehensive new example! The spatialwalk-avatar implementation demonstrates solid architectural patterns with Redux state management and modular component structure. However, there are several important issues that should be addressed before merging. 🔴 Critical Security Issues1. XSS Vulnerability in Image RenderingFile: <img src={data.text} alt="chat" className="w-full" />Risk: Direct Recommendation: Add URL validation/sanitization: const isValidImageUrl = (url: string) => {
try {
const parsed = new URL(url);
return ['http:', 'https:', 'data:'].includes(parsed.protocol);
} catch {
return false;
}
};
// In component:
{data.text && isValidImageUrl(data.text) && (
<img src={data.text} alt="chat" className="w-full" />
)}2. Unsafe window.open() UsageFile: window.open(actionData.url, "_blank");Risk: Opens URLs without validation - potential for phishing/malicious redirects. Recommendation: Validate URLs before opening and add user confirmation for external links. 3. Unsafe JSON ParsingFile: const { stream_id, is_final, text, text_ts, data_type, role } =
JSON.parse(this.base64ToUtf8(completeMessage));Risk: No error handling - malformed JSON crashes the application. Recommendation: Wrap in try-catch and validate structure: try {
const decoded = this.base64ToUtf8(completeMessage);
const parsed = JSON.parse(decoded);
// Validate structure with Zod schema
const validated = messageSchema.parse(parsed);
// Use validated data
} catch (error) {
console.error("Invalid message format:", error);
return; // Gracefully handle
}4. Missing Input Validation in API RouteFile: const body = await request.json();
const { request_id, channel_name, user_uid, graph_name, ... } = body;Risk: No schema validation - accepts any malformed input. Recommendation: Use Zod (already in dependencies) for validation: import { z } from 'zod';
const startRequestSchema = z.object({
request_id: z.string().uuid(),
channel_name: z.string().min(1),
user_uid: z.number().int().positive(),
graph_name: z.string().min(1),

PR Review: Spatialwalk Avatar ExampleOverviewThis PR adds a new example demonstrating integration of a 3D animated avatar (spatialwalk) with the TEN Agent framework. The implementation includes a Next.js frontend with RTC/RTM communication and a complex module configuration system. While the feature is impressive, there are several critical security issues and code quality concerns that need to be addressed before merging. 🔴 Critical Issues (Must Fix Before Merge)1. Exception Handling Anti-patternLocation: throw "Environment variables are not available"; // ❌ WRONGIssue: Throwing a string instead of Error object breaks error handling contracts. Impact: The catch block at line 44 checks Fix: throw new Error("Environment variables are not available");2. Unvalidated Arbitrary URL Opening (Security Vulnerability)Location: if (action === "browse_website") {
console.log("Opening website", actionData.url);
window.open(actionData.url, "_blank"); // ❌ Security Risk
return;
}Issue: Opens any URL received from remote messages without validation. Risk: A malicious or compromised server could inject:
Fix: Add URL validation: if (action === "browse_website") {
const url = actionData.url;
// Validate URL
try {
const parsed = new URL(url);
if (!['http:', 'https:'].includes(parsed.protocol)) {
console.error('Invalid protocol:', parsed.protocol);
return;
}
// Optional: Add domain whitelist
console.log("Opening website", url);
window.open(url, "_blank");
} catch (e) {
console.error('Invalid URL:', url);
}
}3. Missing Error Handling in JSON Parsing (DoS Risk)Location: const { stream_id, is_final, text, text_ts, data_type, role } =
JSON.parse(this.base64ToUtf8(completeMessage)); // ❌ No try-catch
// ...
const { data, type } = JSON.parse(text); // ❌ No try-catchIssue: JSON.parse on untrusted data without error handling will crash the application on malformed messages. Fix: Already wrapped in try-catch at line 330, but should validate the structure: try {
const parsed = JSON.parse(this.base64ToUtf8(completeMessage));
if (!parsed.stream_id || !parsed.text_ts) {
console.error('Invalid message structure');
return;
}
const { stream_id, is_final, text, text_ts, data_type, role } = parsed;
// ...
}4. Committed .env File (Security)Location: Issues:
Fix:
🟠 High Priority Issues5. No Input Validation on API EndpointLocation: The endpoint accepts and forwards all request parameters without validation:
Recommendation: Add input validation with a schema validator (zod, joi, etc.) 6. Memory Leak in Event ListenersLocation: this._client?.removeEventListener("message", this.handleRtmMessage.bind(this));Issue: Fix: Store bound functions as instance members: constructor() {
this.boundHandleRtmMessage = this.handleRtmMessage.bind(this);
}
// Then use:
this._client.addEventListener("message", this.boundHandleRtmMessage);
this._client.removeEventListener("message", this.boundHandleRtmMessage);7. AudioContext Memory LeakLocation: const ctx = new AudioContext();
// No cleanup on unmountCreates a new AudioContext on each track change but never closes it. Fix: useEffect(() => {
const ctx = new AudioContext();
// ... use ctx
return () => ctx.close();
}, [/* deps */]);8. Sensitive Data LoggingLocation: Multiple files // rtc.ts:287
console.log(`[test] message_id: ${message_id} stream_id: ${stream_id}...`);
// rtm/index.ts:56
console.log("[RTM] [TRTMMessageEvent] RAW", JSON.stringify(e));Issue: Logs may contain tokens, user data, or sensitive message content. Fix: Use proper log levels and sanitize sensitive data before logging. 🟡 Code Quality Issues9. Zero Test Coverage
Recommendation: Add tests for at least:
10. Type Safety Issues
11. Race Condition in Avatar InitializationLocation: Module-level mutable state shared across component instances: let initKey: string | null = null;
let initPromise: Promise<void> | null = null;If multiple components mount simultaneously, SDK cleanup might be called while another instance is initializing. 12. Inefficient Deep CloneLocation: const selectedGraphCopy: Graph = JSON.parse(JSON.stringify(selectedGraph));Using JSON serialization for cloning is slow and loses methods.

Pull Request Review: Spatialwalk Avatar ExampleOverviewThis PR adds a new comprehensive example application (spatialwalk-avatar) to the TEN framework, implementing a voice assistant with real-time avatar capabilities using Agora RTC, Deepgram STT, OpenAI LLM, and ElevenLabs TTS. Scale: 166 files, 22,833 additions | Type: New example application Critical Issues1. Environment File Committed to RepositoryLocation: frontend/.env The .env file should NEVER be committed to the repository. Please remove it and create frontend/.env.example instead. 2. Missing Error Response ValidationLocation: frontend/src/common/request.ts Most API functions don't validate response codes. Only apiGetDocumentList checks resp.code. Add validation to all API functions. 3. Inadequate Error Handling in API RouteLocation: frontend/src/app/api/agents/start/route.tsx:16-17 Throwing a string instead of an Error object. Should return proper NextResponse with error details. Significant Issues4. Overly Permissive Type UsageExtensive use of 'any' type throughout frontend/src/common/request.ts defeats TypeScript safety. Define proper response interfaces. 5. Incorrect Error Handling PatternLocation: frontend/src/app/api/agents/start/route.tsx:43-52 Checks for 'error instanceof Response' but axios throws AxiosError, not Response. This catch block will never work correctly. 6. Hardcoded Base DirectoryMultiple functions use hardcoded base_dir: "." which may not work in all deployments. Minor Issues

The implementation demonstrates excellent understanding of the TEN Framework conventions and includes well-structured React/Next.js code with Agora RTC integration. 🎯 Overall AssessmentStatus: APPROVE WITH REQUIRED CHANGES The codebase is fundamentally sound with good architectural patterns, but there are several security and code quality issues that should be addressed before merging. 🔴 Critical Issues (Must Fix)1. Unvalidated JSON Parsing in RTM MessagesFile: const msg: IRTMTextItem = JSON.parse(message as string);Issue: No validation of parsed JSON structure, potential for injection attacks. Fix: try {

Code Review - PR #2043: Feat/spatialwalkThank you for this substantial contribution! This PR adds 166 files with a well-architected Next.js/React frontend. However, I have identified several security vulnerabilities and code quality issues that should be addressed before merging. 🔴 Critical Security Issues1. XSS Vulnerability - Unvalidated window.open()Location: The URL comes from untrusted stream data without validation. This allows execution of arbitrary JavaScript via javascript:, data:, or vbscript: protocols. Fix: Validate URL protocol before opening: if (action === "browse_website") {
const url = new URL(actionData.url);
const allowedProtocols = ["http:", "https:"];
if (!allowedProtocols.includes(url.protocol)) {
console.error("Invalid URL protocol:", url.protocol);
return;
}
window.open(url.href, "_blank");
}2. Unsafe JSON Parsing Without ValidationLocations: JSON parsing on untrusted data without try-catch or schema validation can cause crashes or type confusion. Use Zod for runtime validation. 3. Missing CSRF Protection on API RoutesLocation: API route accepts POST from any origin, vulnerable to CSRF attacks. Add origin/referer validation. 4. Unvalidated URL ParametersLocation: URL parameter avatarId is used without validation. Add regex validation for expected format. 🟡 High Priority Issues

SummaryThis is a well-structured feature with good architectural decisions. However, the security vulnerabilities (especially the XSS risk in window.open()) must be addressed before merging to production. Recommendation: Request changes for critical security issues, then approve once addressed. |
PR #2043 Code Review: Spatialwalk-Avatar Example AgentThank you for this contribution! I've conducted a comprehensive review of the PR. Below are my findings organized by category. 🔴 Critical Security Issues1. Environment File Not Properly IgnoredLocation: The Recommendation:
2. No Input Validation in API RouteLocation: The API endpoint accepts all request body fields without validation: const { request_id, channel_name, user_uid, graph_name, language, voice_type, properties } = body;Recommendation: Add schema validation using Zod or similar: import { z } from 'zod';
const startAgentSchema = z.object({
request_id: z.string().uuid(),
channel_name: z.string().min(1),
user_uid: z.number().int().positive(),
graph_name: z.string().min(1),
// ... etc
});3. XSS Vulnerability RiskLocation: User-controlled content is directly used as image URL without validation: <img src={data.text} alt="chat" className="w-full" />Recommendation: Validate URLs against a whitelist of allowed protocols/domains, or use a Content Security Policy. 4. Plaintext Credential StorageLocation: Sensitive data stored in localStorage without encryption: localStorage.setItem(OPTIONS_KEY, JSON.stringify(options));Recommendation: Use secure, httpOnly cookies for auth tokens, or implement encryption for localStorage values.

Pull Request Review: Spatialwalk Avatar ExampleThank you for this comprehensive contribution! This PR adds 167 files with 22,830 additions. I've completed a thorough security and code quality review. Critical Security Vulnerabilities1. Unsafe JSON.parse Without Validation - XSS RiskLocation: frontend/src/manager/rtc/rtc.ts:285, 300 Parsing untrusted RTC stream messages without validation could lead to prototype pollution. No try-catch around JSON.parse can crash the application. Parsed text is directly used in UI without sanitization. window.open() can be triggered from remote messages without user confirmation. Recommendation: Add Zod schema validation, wrap in try-catch, sanitize all text before rendering. 2. Insecure Type Coercion in Error ChecksLocation: rtc.ts:70, 92, Action.tsx:50, 97, 98 Using == instead of === allows type coercion. API returns both string "0" and number 0 in different places. Recommendation: Use strict equality (===) everywhere and ensure consistent API response types. 3. Weak Random Number GenerationLocation: frontend/src/common/utils.ts:17-18 Math.random() is not cryptographically secure. Only 6-digit range makes user IDs easily guessable. Recommendation: Use crypto.getRandomValues() for cryptographically secure random generation. 4. Unsafe localStorage Without ValidationLocation: frontend/src/common/storage.ts:13, 29 localStorage can be poisoned by XSS attacks. Recommendation: Add schema validation for all localStorage data. 5. No Input Validation on API RequestsLocation: frontend/src/common/request.ts Properties object passed to backend without validation. Recommendation: Add input validation using Zod before sending to API. 6. Prototype Pollution in Deep MergeLocation: frontend/src/common/utils.ts:92-103 No safeguards against proto, constructor, prototype keys. Recommendation: Add checks to skip dangerous keys or use a battle-tested library. Code Quality Issues7. Poor Error HandlingThrowing strings instead of Error objects. Many async functions lack try-catch blocks. Recommendation: Always throw Error objects, add proper error handling and error boundaries. 8. Memory Leak Risks in RTC ManagerLocation: frontend/src/manager/rtc/rtc.ts:268-273 Timeouts not cleared when component unmounts. messageCache grows unbounded. Recommendation: Track timeouts and clear them in cleanup, add max cache size limits. 9. Race Condition in Ping IntervalLocation: frontend/src/components/Layout/Action.tsx:115-129 Module-level variable can cause issues with multiple instances. Recommendation: Move to component state, add cleanup in useEffect return. 10. Inconsistent Type SafetyMany functions return Promise. Extensive use of any type (37+ occurrences). Recommendation: Define proper TypeScript interfaces for all API responses. 11. Missing CSRF ProtectionSeverity: MEDIUM No CSRF tokens on state-changing operations. Recommendation: Implement CSRF protection for all state-changing endpoints. Performance Concerns12. Inefficient State Updates in ReduxLocation: frontend/src/store/reducers/global.ts:186-191 Expensive deep clone using JSON stringify/parse. Redux Toolkit includes Immer. Recommendation: Remove manual cloning, use direct mutation (Immer handles it). 13. Missing Dependency Array ItemsLocation: frontend/src/components/Layout/Action.tsx:46 Recommendation: Include all dependencies or use useCallback for stable references. Best Practice Violations14. Environment Variables Not ValidatedNo check if URLs are valid format. Recommendation: Validate URL format, not just existence. 15. Console Logging in Production67+ console statements will leak data in production. Recommendation: Remove or gate behind development checks. 16. No Content Security PolicyNo CSP headers to prevent XSS attacks. Recommendation: Add CSP headers in next.config.mjs. 17. .env File CommittedThe .env file is committed which could expose secrets. Recommendation: Move to .env.example and ensure .env is in .gitignore. Positive Aspects

Code Review: PR #2043 - Spatialwalk Avatar ExampleThank you for this substantial contribution adding the spatialwalk-avatar example with 23,516 additions across 185 files. I've conducted a comprehensive review covering security, code quality, best practices, and potential bugs. SummaryOverall Assessment: ⭐⭐⭐⭐ (4/5) The code is generally well-structured with good React patterns and proper component architecture. However, there are several security hardening opportunities and code quality improvements needed before production deployment. Risk Level: MODERATE 🔴 Critical Issues (Must Address)1. Missing Input Validation in API Route HandlerLocation: Issue: The API route accepts and forwards user input to the backend without any validation or sanitization. const body = await request.json();
const { request_id, channel_name, user_uid, graph_name, language, voice_type, properties } = body;
// ❌ No validation before forwarding
const response = await axios.post(`${AGENT_SERVER_URL}/start`, {
request_id, channel_name, user_uid, graph_name, properties: properties
});Risk: Malicious payloads could be injected through the Recommendation:
2. Sensitive Data Exposure via URL ParametersLocation: Issue: Sensitive configuration data (appId, avatarId) is read from URL query parameters. const params = new URLSearchParams(window.location.search);
return {
appId: params.get("appId")?.trim() || "",
avatarId: params.get("avatarId")?.trim() || "",
};Risk: These IDs can be leaked via:
Recommendation:
3. Insecure Dockerfile PatternsLocations:
Issue: Using curl-to-bash pattern without checksum verification, running as root. Risk: If the source is compromised, malicious code could be executed during build. Recommendation: # Use specific version with checksum verification
RUN wget https://nodejs.org/dist/v20.x.x/node-v20.x.x-linux-x64.tar.xz \
&& echo "EXPECTED_CHECKSUM node-v20.x.x-linux-x64.tar.xz" | sha256sum -c - \

Documentation:
🔴 Critical Issues - Must Fix Before Merge1. Security: Missing Input Validation (HIGH)Location: The spatialwalk IDs from URL parameters lack proper validation: appId: params.get("appId")?.trim() || "",
avatarId: params.get("avatarId")?.trim() || "",Recommendation: Add validation:
2. Security: SSRF Potential in API Routes (HIGH)Location: API routes proxy requests to const response = await axios.post(`${AGENT_SERVER_URL}/start`, {...})Recommendation:
3. Security: No Authentication on API Routes (HIGH)Location: The API routes appear to lack authentication:
Recommendation:
4. Missing Test Coverage (CRITICAL)This PR adds zero test files for 24k+ lines of code. Recommendation: Add at minimum:
🟡 High Priority Issues - Should Fix5. Environment Variable SecurityLocation: COPY .env.example .envThis approach is risky for production deployments. Recommendation:
6. Code Quality: Loose EqualityLocation: Multiple files (e.g., response validation) if (resp?.code == 0) { // loose equalityRecommendation: Use strict equality ( 7. Error Handling Lacks SpecificityLocation: Generic error responses don't distinguish error types: return NextResponse.json(
{ code: "1", data: null, msg: "Internal Server Error" },
{ status: 500 }
