Output:
【漏洞类型】未验证的用户输入
【严重性】Medium
【漏洞摘要】原始代码中的`updateDocumentTitleAndContentFromRequest`方法未对用户输入的标题或内容进行验证或清理。这可能导致攻击者通过修改文档标题或内容注入恶意脚本或数据，进而可能利用这些数据进行跨站脚本攻击（XSS）或其他形式的攻击。
【关键代码模式】`updateDocumentTitleAndContentFromRequest`方法中的`editForm.getContent()`和`editForm.getTitle()`。
【修复方法说明】修复方法通过检查文档的元数据和内容是否被修改，并在修改时更新作者信息，解决了未验证用户输入的问题。这遵循了最佳实践中的输入验证和最小权限原则。

Output:
【漏洞类型】跨站请求伪造（CSRF）和远程代码执行（RCE）
【严重性】High
【漏洞摘要】在原始代码中，`EditAction` 类处理文档的编辑请求时，没有对请求中的 CSRF 令牌进行验证。这可能导致攻击者通过 CSRF 攻击提交恶意请求，从而在未经授权的情况下修改或创建文档。此外，如果文档内容或元数据被修改，代码中没有进一步的验证措施，这可能为潜在的 RCE 漏洞（例如，通过脚本注入）提供机会。具体问题出现在 `prepareEditedDocument` 方法中，特别是对 `editForm.getContent()` 和 `editForm.getTitle()` 的处理。
【关键代码模式】未验证的 CSRF 令牌，直接使用用户输入更新文档内容和元数据。
【修复方法说明】修复方法通过在 `prepareEditedDocument` 方法中添加 CSRF 令牌验证，确保只有在提供有效 CSRF 令牌的情况下，文档内容和元数据才会被更新，从而防止 CSRF 攻击。

Output:
【漏洞类型】输入验证缺失漏洞
【严重性】中等
【漏洞摘要】原始代码在生成文档查看URL时，未对请求参数`$request.rev`进行适当的编码或验证，可能允许攻击者通过修改`$request.rev`参数注入恶意内容。这可能导致路径遍历、XSS（跨站脚本攻击）或其他形式的安全问题。

【关键代码模式】
- 未验证的用户输入：`$request.rev`
- 直接在URL中使用用户输入：`#set ($revisionParameter = "&rev=$request.rev")`
- `getURL`函数的使用，可能依赖于未验证的参数：`$doc.getURL('view', "viewer=code$!{revisionParameter}")`

【修复方法说明】
通过使用`$escapetool.url`对请求参数`$request.rev`进行编码，防止了潜在的XSS和路径遍历攻击。最佳实践是在处理用户输入时，始终进行适当的编码和验证。
