Output:
【漏洞类型】反序列化漏洞
【严重性】High
【漏洞摘要】此代码中的反序列化操作存在安全风险。具体表现为`PayloadUtil.deserialize`和`WorkBundle.readFromStream`函数中，未经验证的用户输入直接被反序列化为对象。这可能导致攻击者通过构造恶意序列化数据来执行任意代码。
【关键代码模式】
- `PayloadUtil.deserialize`函数
- `WorkBundle.readFromStream`函数
- `ObjectInputStream`的使用
- `WorkUnit.readFromStream`函数
- `DataInputStream`的使用
【修复方法说明】修复方法通过移除`MoveToAdapter`类和相关的反序列化操作，转而使用更安全的`DataInput/DataOutputStream`进行序列化和反序列化。同时，添加了对`WorkBundle`中`WorkUnit`数量的限制，以防止反序列化过程中处理过多的对象。

Output:
【漏洞类型】路径遍历漏洞
【严重性】High
【漏洞摘要】原始代码中存在路径遍历漏洞，主要是由于未验证的用户输入导致。具体表现为在`getPointsFromRequest`方法中，使用了`String url = httpServletRequest.getRequestURI();`获取请求的URI，然后使用正则表达式`url.replaceFirst("/navigate/directions/v5/gh/" + profile + "/", "");`和`url.replaceAll("\\?[*]", "");`对URI进行处理，这使得攻击者可以构造恶意的URI来遍历文件系统。根本原因是对用户输入的URI没有进行严格的验证和清理。
【关键代码模式】与用户输入相关的代码模式，特别是涉及字符串操作和路径处理的代码。关键词包括`HttpServletRequest.getRequestURI()`、`String.replaceFirst()`、`String.replaceAll()`、路径遍历。
【修复方法说明】通过替换正则表达式，使用`String.startsWith()`和`String.substring()`来验证和清理URI，从而防止路径遍历漏洞。适用的最佳实践是严格验证和清理用户输入，避免使用正则表达式进行路径处理。
