Output:
【漏洞类型】跨站脚本攻击（XSS）
【严重性】High
【漏洞摘要】此代码存在一个跨站脚本攻击（XSS）漏洞，攻击者可以通过构造恶意的URL中的文件名（`$Request->Path()`）来执行任意客户端代码。具体表现为，原始代码在`EntryController::Handshake()`和`Dispatcher::_AnalyzeRequest()`中使用了未验证的用户输入作为`$this->SelfUrl`和`$this->Request`的值。这样，恶意用户可以注入JavaScript代码到URL中，从而在用户的浏览器中执行。
【关键代码模式】与此漏洞相关的关键代码模式包括：
- 使用用户输入的`$Request->Path()`来设置`$this->SelfUrl`和`$this->Request`。
- `$this->SelfUrl = Gdn::Request()->Path();`
- `$this->Request = $Request->Path();`
【修复方法说明】修复方法通过将`$Request->Path()`替换为`Url('')`来解决问题，确保不会直接使用用户输入的URL路径进行渲染。这遵循了最佳实践，即对用户输入进行适当的验证和编码，以防止XSS攻击。

Output:
【漏洞类型】未验证的用户输入
【严重性】High
【漏洞摘要】此代码中存在未验证用户输入的安全漏洞。在`AsyncMacro`类的`execute`方法中，`parameters.getDocument()`参数直接用于解析和执行宏内容，而没有进行任何访问控制检查。如果攻击者能够控制`parameters.getDocument()`的值，他们可能会执行在他们有权访问的文档中定义的宏，包括潜在的恶意脚本宏。这可能导致未经授权的访问或执行。
【关键代码模式】
- `parameters.getDocument()`
- `this.documentAccessBridge.pushDocumentInContext(backupObjects, referencedDocReference)`
- `this.transformationManager.performTransformations(xdom, txContext)`

这些代码模式和关键词表明了未验证用户输入的问题，特别是在文档引用的解析和上下文切换过程中。
【修复方法说明】通过引入`AuthorizationManager`进行访问控制检查，确保只有具有适当权限的用户才能执行特定文档中的宏内容。这解决了未验证用户输入的安全漏洞，提高了系统的安全性。
