+
+## 二、发现的问题
+
+### 严重 (High)
+
+#### 1. 错误密码登录返回200
+- **位置**: `POST /api/v1/auth/login`
+- **描述**: 使用错误密码登录时返回 HTTP 200，应返回 401
+- **影响**: 可能导致暴力破解攻击难以被检测
+- **建议**: 检查登录逻辑，确保密码错误时返回 401
+
+#### 2. XSS 内容被原样存储
+- **位置**: `POST /api/v1/courses` (name, description 字段)
+- **描述**: `<script>alert(1)</script>` 等 XSS 代码被原样存入数据库
+- **影响**: 潜在的存储型 XSS 攻击风险
+- **建议**: 
+  - 输入时转义或过滤 HTML 标签
+  - 输出时使用 HTML 实体编码
+
+### 中等 (Medium)
+
+#### 3. 不存在用户登录返回422
+- **位置**: `POST /api/v1/auth/login`
+- **描述**: 登录不存在的用户返回 422，应返回 401
+- **影响**: 用户枚举风险（可判断用户是否存在）
+- **建议**: 统一返回 401 "用户名或密码错误"
+
+#### 4. API 限流未配置
+- **位置**: 全局
+- **描述**: 10次快速请求未触发限流
+- **影响**: 可能被恶意请求攻击
+- **建议**: 配置 API 限流中间件
+
+### 低等 (Low)
+
+#### 5. 越权访问返回404而非403
+- **位置**: `GET /api/v1/admin/users`
+- **描述**: 普通用户访问管理接口返回 404 而非 403
+- **影响**: 信息泄露（可探测接口是否存在）
+- **建议**: 统一返回 403 Forbidden
+
+#### 6. 部分API端点404
+- **位置**: 
+  - `GET /api/v1/exams` (考试列表)
+  - `GET /api/v1/practice/sessions` (练习记录)
+- **描述**: 这些端点返回 404，可能是路径变更或未实现
+- **建议**: 确认 API 路径或补充实现
