Summary

This PR adds a comprehensive security and code audit report identifying 55 issues across the codebase:

Critical Security Issues (5)

  • Command injection vulnerability in git.js
  • Hardcoded JWT secret
  • JWT token never expires
  • XSS vulnerability in PRDEditor.jsx
  • Plaintext credential storage

Major Issues (6)

  • Monolithic files (index.js 1930 lines)
  • Zero test coverage
  • Path traversal vulnerability
  • Missing await on async calls
  • Unhandled WebSocket JSON parsing errors
  • Uncaught Projects Watcher startup failures

Recommendations

  • Database indexing for query optimization
  • React.memo for components
  • Structured logging
  • Streaming for large file reads

Test Plan

  • Review the audit report
  • Prioritize critical fixes
  • Address security vulnerabilities in follow-up PRs

Poem

🐰 A hop through the code, what dangers we find!
Command injections and secrets, not well-defined,
The audit reveals where the bugs love to hide,
With fixes and guidance to strengthen our stride,
Security hardened, we hop on with pride!

1-1: Move the report out of the repository root into docs/security/.

Audit reports placed at the repository root create clutter and are typically scoped under docs/ or docs/security/ in well-organized projects. This also makes it easier to co-locate future audit reports, threat models, and security policies.

⚠️ Potential issue | 🟡 Minor

No GitHub Issues linked for any of the 55 reported findings.

Contributing.md requires PRs to "reference issue numbers" and "link related issues." A security audit report that doesn't link to tracking issues provides no accountability or remediation workflow — findings become stale documentation with no owner.

For each critical and major finding, a corresponding GitHub Issue (or private Security Advisory, per the comment above) should be created and referenced here before this report is merged.

As per coding guidelines: "reference issue numbers, describe how to reproduce bugs".

## 🔴 严重问题 (需立即修复)

### 1. 命令注入漏洞 (CRITICAL)

**位置**: server/routes/git.js 多处

**危险代码示例**:
```javascript
await execAsync(`git commit -m "${message}"`) // 第379行
await execAsync(`git status --porcelain "${file}"`) // 第205行
```

**修复建议**: 改用 spawnAsync + 参数数组

---

### 2. 硬编码 JWT 密钥 (CRITICAL)

**位置**: server/middleware/auth.js:6

```javascript
const JWT_SECRET = process.env.JWT_SECRET ||
'claude-ui-dev-secret-change-in-production'
```

**修复建议**: 生产环境必须设置 JWT_SECRET 环境变量

---

### 3. JWT Token 永不过期 (CRITICAL)

**位置**: server/middleware/auth.js:69-79

**修复建议**: 添加 `{ expiresIn: '24h' }`

---

### 4. XSS 漏洞 (CRITICAL)

**位置**: src/components/PRDEditor.jsx:492-504

**问题**: Markdown 解析器未转义 HTML,用户输入可执行恶意脚本

---

### 5. 凭据明文存储 (CRITICAL)

**位置**: server/database/db.js:196-267

**问题**: API 密钥、GitHub Token 以明文存储

---

## 🟡 重大问题

| 问题 | 位置 | 类型 |
|------|------|------|
| 巨型文件 (index.js 1930行) | server/ | 代码质量 |
| 零测试覆盖 | src/, server/ | 测试 |
| 路径遍历漏洞 | server/routes/commands.js:466-477 | 安全 |
| 异步未 await | server/routes/agent.js:886 | Bug |
| WebSocket JSON 解析无错误处理 | server/index.js:929-1040 | Bug |
| Projects Watcher 启动失败无捕获 | server/index.js:1921-1922 | Bug |

---

## 🟢 建议改进

- 添加数据库索引优化查询性能
- 前端 WebSocket 消息添加节流
- React 组件使用 React.memo
- 大文件读取使用流式处理
- 使用结构化日志替代 console.log
- 移除代码中的 Emoji

⚠️ Potential issue | 🟡 Minor

Document should be written in English to match the project's documentation language.

The entire report is in Chinese (Simplified), while all project documentation (Contributing.md, README, PR descriptions) is in English. This limits accessibility for the wider contributor base.

If an English version is intended downstream, consider adding it now alongside or instead of the Chinese text.

⚠️ Potential issue | 🟠 Major

Do not publicly commit unpatched vulnerability details — use GitHub Security Advisories instead.

This section documents 5 CRITICAL unresolved vulnerabilities with exact file paths, line numbers, and vulnerable code snippets (command injection, hardcoded JWT secret, JWT non-expiry, XSS, plaintext credential storage). Committing this to a public repository before fixes are in place is a responsible disclosure violation — it hands adversaries a ready-made exploit map.

The correct workflow:

  1. Use GitHub's private Security Advisory feature (Settings → Security → Advisories → New draft) to track each finding privately until patches are merged.
  2. Publish the advisory only after corresponding fixes land.

If the intent is to track these as regular work items, create individual GitHub Issues (not a public document exposing vulnerability specifics) and implement the fixes before or alongside disclosure.
