Original Cubic page · captured 2026-09-23 · source commit. This AI-generated page has not been verified against the current code. Use the Zhin documentation for current behavior and see known corrections.

Known correction

New scaffolded projects currently configure HTTP port 8068; 8086 is the fallback when the runtime has no configured port. Built-in Agent defaults are execSecurity: deny and execApprovalMode: auto; explicit project configuration may override them. Check the startup output or http.port. See Getting Started.

Security Policy & Best Practices

Zhin.js implements a multi-layered security model to protect its plugin-based architecture and AI agent execution environment. This policy outlines how to report vulnerabilities, manage credentials, and implement secure plugin logic within the framework.

Vulnerability Reporting & Response

The Zhin.js team prioritizes the resolution of security issues. You should disclose vulnerabilities privately rather than through public GitHub Issues.

Reporting Channels

• Preferred Method: Email findings to security@zhin.dev.
• Alternative: Use the GitHub Security Advisory private reporting feature.

Response Timeline

The team follows a structured timeline for vulnerability assessment and patching:

1. Acknowledgment: Within 48 hours of receipt.
2. Initial Assessment: Within 5 business days, including an estimated fix timeline.
3. Fix Release:
   • Critical Severity: 7-14 days.
   • Medium Severity: 14-30 days.
   • Low Severity: 30-60 days.

User Best Practices

Users managing Zhin.js instances must maintain environment hygiene and restrict access to management interfaces.

Credential Protection

• Environment Variables: Store sensitive keys in a .env file and reference them in zhin.config.yml using the ${VAR_NAME} syntax.
• Version Control: Never commit .env files to git; the project includes .env in the default .gitignore.
• HTTP Tokens: Use a strong HTTP_TOKEN for the Web Console. The scaffold-wizard generates a random 32-character hex string by default.

Access Control

• Host API: Restrict the Host API (default :8086) to trusted sources using firewall rules or reverse proxies like Nginx.
• Production Configuration: Disable file watching in production by setting NODE_ENV=production to prevent exhaustion of system resources (inotify limits).

The diagram shows the authentication flow for accessing the Host API via the Remote Console.

Developer Security Guidelines

Plugin developers are responsible for sanitizing inputs and preventing injection attacks within the Zhin.js runtime.

Input Validation

Always validate and sanitize user input. Zhin.js provides a Schema system for type checking and range validation.

import { Schema } from '@zhin.js/schema'

const Input = Schema.object({
  url: Schema.string().pattern(/^https?:\/\//),
  count: Schema.number().min(1).max(100)
})
const input = Input(untrustedInput)

Sources: SECURITY.md:273-282

Injection Prevention

Developers must use parameterized queries for database operations. Concatenating strings into SQL queries is strictly prohibited.

• Correct: db.model('users').findOne({ where: { id: userId } })
• Incorrect: db.query("SELECT * FROM users WHERE id = " + userId)

Sources: SECURITY.md:284-290

Error Handling

Do not leak sensitive stack traces or internal configuration to chat channels. Use generic error messages for end-users while logging detailed errors to the internal logger.

Agent Security Architecture

The Zhin.js Agent orchestrator includes high-level security policies to govern tool execution and resource access.

Execution & File Policies

Agent security is enforced through two primary policy layers:

• ExecPolicy: Governs shell command execution through five levels of defense (e.g., allowlists).
• FilePolicy: Restricts filesystem access through four levels of defense, preventing path traversal.

Tool Security Configuration

Built-in tools default to strict security settings:

• execSecurity: Defaults to deny.
• execApprovalMode: Defaults to auto.

This diagram illustrates the sequence of security checks performed before an AI Agent executes a system tool.

Known Security Considerations

Feature	Security Risk	Mitigation
Plugin System	Plugins run in the same process with full system access.	Install plugins only from trusted sources.
Hot Reload	May lead to unauthorized code execution in compromised environments.	Disable in production environments.
Remote Console	Default listening on 0.0.0.0 exposes the interface.	Restrict to 127.0.0.1 or use a reverse proxy with HTTPS.
File Watching	Resource exhaustion (inotify).	Avoid watching node_modules; specify exact plugin directories.

Security Roadmap

The framework plans to introduce the following enhancements in future versions:

• Fine-grained Plugin Permissions: A system for limiting specific plugin capabilities.
• Code Signing: Verification of plugin integrity before loading.
• Two-Factor Authentication (2FA): Enhanced security for the Remote Console.
• Sandbox Isolation: Executing plugins in isolated environments rather than the main process.
