安全审查技能
此技能确保所有代码遵循安全最佳实践,并识别潜在漏洞。
何时激活
- 实现身份验证或授权时
- 处理用户输入或文件上传时
- 创建新的 API 端点时
- 处理密钥或凭据时
- 实现支付功能时
- 存储或传输敏感数据时
- 集成第三方 API 时
安全检查清单
1. 密钥管理
❌ 绝对不要这样做
const apiKey = "sk-proj-xxxxx" // Hardcoded secret const dbPassword = "password123" // In source code
✅ 始终这样做
const apiKey = process.env.OPENAI_API_KEY const dbUrl = process.env.DATABASE_URL // Verify secrets exist if (!apiKey) { throw new Error('OPENAI_API_KEY not configured') }
验证步骤
- [ ] 没有硬编码的 API 密钥、令牌或密码
- [ ] 所有密钥都存储在环境变量中
- [ ]
文件在 .gitignore 中.env - [ ] git 历史记录中没有密钥
- [ ] 生产环境密钥存储在托管平台中(Vercel, Railway)
2. 输入验证
始终验证用户输入
import { z } from 'zod' // Define validation schema const CreateUserSchema = z.object({ email: z.string().email(), name: z.string().min(1).max(100), age: z.number().int().min(0).max(150) }) // Validate before processing export async function createUser(input: unknown) { try { const validated = CreateUserSchema.parse(input) return await db.users.create(validated) } catch (error) { if (error instanceof z.ZodError) { return { success: false, errors: error.errors } } throw error } }
文件上传验证
function validateFileUpload(file: File) { // Size check (5MB max) const maxSize = 5 * 1024 * 1024 if (file.size > maxSize) { throw new Error('File too large (max 5MB)') } // Type check const allowedTypes = ['image/jpeg', 'image/png', 'image/gif'] if (!allowedTypes.includes(file.type)) { throw new Error('Invalid file type') } // Extension check const allowedExtensions = ['.jpg', '.jpeg', '.png', '.gif'] const extension = file.name.toLowerCase().match(/\.[^.]+$/)?.[0] if (!extension || !allowedExtensions.includes(extension)) { throw new Error('Invalid file extension') } return true }
验证步骤
- [ ] 所有用户输入都使用模式进行了验证
- [ ] 文件上传受到限制(大小、类型、扩展名)
- [ ] 查询中没有直接使用用户输入
- [ ] 使用白名单验证(而非黑名单)
- [ ] 错误消息不会泄露敏感信息
3. SQL 注入防护
❌ 绝对不要拼接 SQL
// DANGEROUS - SQL Injection vulnerability const query = `SELECT * FROM users WHERE email = '${userEmail}'` await db.query(query)
✅ 始终使用参数化查询
// Safe - parameterized query const { data } = await supabase .from('users') .select('*') .eq('email', userEmail) // Or with raw SQL await db.query( 'SELECT * FROM users WHERE email = $1', [userEmail] )
验证步骤
- [ ] 所有数据库查询都使用参数化查询
- [ ] SQL 中没有字符串拼接
- [ ] 正确使用 ORM/查询构建器
- [ ] Supabase 查询已正确清理
4. 身份验证与授权
JWT 令牌处理
// ❌ WRONG: localStorage (vulnerable to XSS) localStorage.setItem('token', token) // ✅ CORRECT: httpOnly cookies res.setHeader('Set-Cookie', `token=${token}; HttpOnly; Secure; SameSite=Strict; Max-Age=3600`)
授权检查
export async function deleteUser(userId: string, requesterId: string) { // ALWAYS verify authorization first const requester = await db.users.findUnique({ where: { id: requesterId } }) if (requester.role !== 'admin') { return NextResponse.json( { error: 'Unauthorized' }, { status: 403 } ) } // Proceed with deletion await db.users.delete({ where: { id: userId } }) }
行级安全(Supabase)
-- Enable RLS on all tables ALTER TABLE users ENABLE ROW LEVEL SECURITY; -- Users can only view their own data CREATE POLICY "Users view own data" ON users FOR SELECT USING (auth.uid() = id); -- Users can only update their own data CREATE POLICY "Users update own data" ON users FOR UPDATE USING (auth.uid() = id);
验证步骤
- [ ] 令牌存储在 httpOnly cookie 中(而非 localStorage)
- [ ] 执行敏感操作前进行授权检查
- [ ] Supabase 中启用了行级安全
- [ ] 实现了基于角色的访问控制
- [ ] 会话管理安全
5. XSS 防护
清理 HTML
import DOMPurify from 'isomorphic-dompurify' // ALWAYS sanitize user-provided HTML function renderUserContent(html: string) { const clean = DOMPurify.sanitize(html, { ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'p'], ALLOWED_ATTR: [] }) return <div dangerouslySetInnerHTML={{ __html: clean }} /> }
内容安全策略
// next.config.js const securityHeaders = [ { key: 'Content-Security-Policy', value: ` default-src 'self'; script-src 'self' 'unsafe-eval' 'unsafe-inline'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self'; connect-src 'self' https://api.example.com; `.replace(/\s{2,}/g, ' ').trim() } ]
验证步骤
- [ ] 用户提供的 HTML 已被清理
- [ ] 已配置 CSP 头部
- [ ] 没有渲染未经验证的动态内容
- [ ] 使用了 React 内置的 XSS 防护
6. CSRF 防护
CSRF 令牌
import { csrf } from '@/lib/csrf' export async function POST(request: Request) { const token = request.headers.get('X-CSRF-Token') if (!csrf.verify(token)) { return NextResponse.json( { error: 'Invalid CSRF token' }, { status: 403 } ) } // Process request }
SameSite Cookie
res.setHeader('Set-Cookie', `session=${sessionId}; HttpOnly; Secure; SameSite=Strict`)
验证步骤
- [ ] 状态变更操作上使用了 CSRF 令牌
- [ ] 所有 Cookie 都设置了 SameSite=Strict
- [ ] 实现了双重提交 Cookie 模式
7. 速率限制
API 速率限制
import rateLimit from 'express-rate-limit' const limiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 100, // 100 requests per window message: 'Too many requests' }) // Apply to routes app.use('/api/', limiter)
昂贵操作
// Aggressive rate limiting for searches const searchLimiter = rateLimit({ windowMs: 60 * 1000, // 1 minute max: 10, // 10 requests per minute message: 'Too many search requests' }) app.use('/api/search', searchLimiter)
验证步骤
- [ ] 所有 API 端点都实施了速率限制
- [ ] 对昂贵操作有更严格的限制
- [ ] 基于 IP 的速率限制
- [ ] 基于用户的速率限制(已认证)
8. 敏感数据泄露
日志记录
// ❌ WRONG: Logging sensitive data console.log('User login:', { email, password }) console.log('Payment:', { cardNumber, cvv }) // ✅ CORRECT: Redact sensitive data console.log('User login:', { email, userId }) console.log('Payment:', { last4: card.last4, userId })
错误消息
// ❌ WRONG: Exposing internal details catch (error) { return NextResponse.json( { error: error.message, stack: error.stack }, { status: 500 } ) } // ✅ CORRECT: Generic error messages catch (error) { console.error('Internal error:', error) return NextResponse.json( { error: 'An error occurred. Please try again.' }, { status: 500 } ) }
验证步骤
- [ ] 日志中没有密码、令牌或密钥
- [ ] 对用户显示通用错误消息
- [ ] 详细错误信息仅在服务器日志中
- [ ] 没有向用户暴露堆栈跟踪
9. 区块链安全(Solana)
钱包验证
import { verify } from '@solana/web3.js' async function verifyWalletOwnership( publicKey: string, signature: string, message: string ) { try { const isValid = verify( Buffer.from(message), Buffer.from(signature, 'base64'), Buffer.from(publicKey, 'base64') ) return isValid } catch (error) { return false } }
交易验证
async function verifyTransaction(transaction: Transaction) { // Verify recipient if (transaction.to !== expectedRecipient) { throw new Error('Invalid recipient') } // Verify amount if (transaction.amount > maxAmount) { throw new Error('Amount exceeds limit') } // Verify user has sufficient balance const balance = await getBalance(transaction.from) if (balance < transaction.amount) { throw new Error('Insufficient balance') } return true }
验证步骤
- [ ] 已验证钱包签名
- [ ] 已验证交易详情
- [ ] 交易前检查余额
- [ ] 没有盲签名交易
10. 依赖项安全
定期更新
# Check for vulnerabilities npm audit # Fix automatically fixable issues npm audit fix # Update dependencies npm update # Check for outdated packages npm outdated
锁定文件
# ALWAYS commit lock files git add package-lock.json # Use in CI/CD for reproducible builds npm ci # Instead of npm install
验证步骤
- [ ] 依赖项是最新的
- [ ] 没有已知漏洞(npm audit 检查通过)
- [ ] 提交了锁定文件
- [ ] GitHub 上启用了 Dependabot
- [ ] 定期进行安全更新
安全测试
自动化安全测试
// Test authentication test('requires authentication', async () => { const response = await fetch('/api/protected') expect(response.status).toBe(401) }) // Test authorization test('requires admin role', async () => { const response = await fetch('/api/admin', { headers: { Authorization: `Bearer ${userToken}` } }) expect(response.status).toBe(403) }) // Test input validation test('rejects invalid input', async () => { const response = await fetch('/api/users', { method: 'POST', body: JSON.stringify({ email: 'not-an-email' }) }) expect(response.status).toBe(400) }) // Test rate limiting test('enforces rate limits', async () => { const requests = Array(101).fill(null).map(() => fetch('/api/endpoint') ) const responses = await Promise.all(requests) const tooManyRequests = responses.filter(r => r.status === 429) expect(tooManyRequests.length).toBeGreaterThan(0) })
