SiYuan Vulnerable to Arbitrary File Read via File Copy Functionality

SiYuan is a personal knowledge management system. Versions prior to 3.5.4 contain a logic vulnerability in the /api/file/globalCopyFiles endpoint. The function allows authenticated users to copy files from any location on the server's filesystem into the application's workspace without proper path validation. The vulnerability exists in the api/file.go source code. The function globalCopyFiles accepts a list of source paths (srcs) from the JSON request body. While the code checks if the source file exists using filelock.IsExist(src), it fails to validate whether the source path resides within the authorized workspace directory. Version 3.5.4 patches the issue.

N/A

对路径名的限制不恰当(路径遍历)

SiYuan 路径遍历漏洞

SiYuan是SiYuan开源的一个隐私至上的个人知识管理系统。 SiYuan 3.5.4之前版本存在路径遍历漏洞，该漏洞源于/api/file/globalCopyFiles端点存在逻辑漏洞，缺少适当的路径验证，可能导致经过身份验证的用户将服务器文件系统上任意位置的文件复制到应用程序工作区。
