优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
在服务器模式下，pgAdmin 4 通过 函数验证用户存储目录中的路径，该函数利用 构建绝对路径。然而，多个调用方以不同的方式构建路径，导致被验证的路径与实际使用的路径可能指向不同的文件： 在查询工具中打开文件、读取 Google 客户端密钥，以及在 Windows 系统上进行导入/导出数据、备份、还原和保存文件时，相关操作会在去除路径前导的斜杠和反斜杠后，再将路径拼接至存储目录。在 POSIX 系统上，原本被验证为位于存储目录内的路径，在去除前导字符后可能变为绝对路径，从而允许 pgAdmin 账户读取其可访问的

Vulnerability Title
pgAdmin 4: File Manager and storage-path tools act on a different path from the one checked
来源: CVE Program / CVE List V5
Vulnerability Description
In server mode pgAdmin 4 validates a path into the user's storage directory with check_access_permission(), which builds the absolute path with get_abs_path(). Several callers then acted on a path they built differently, so the path checked and the path used could name different files:
- Opening a file in the Query Tool, the Google client secret and, on Windows, Import/Export Data, Backup, Restore and saving a file joined the path to the storage directory after stripping leading slashes and backslashes. On POSIX a path checked as a name inside storage could become an absolute path once stripped, so any file the pgAdmin account can read could be opened; on Windows a path naming a drive discarded the storage directory, so these could read, or write, outside it.
- Listing a folder decoded the path a second time after the check, so a folder named like an encoded "..", which a user can create, listed any directory on the host.
- Download, delete, rename and the file-exists check appended the path to the storage directory without a separator, so in a deployment where one user's storage directory name is a prefix of another's, another user's files could be read, deleted or moved; download also checked the path appended to itself.
- Creating a folder could create one in another user's directory.
The fix makes check_access_permission() return the path it checked and every caller act on that path, decodes folder paths once, and opens, deletes and renames files relative to directories opened from the storage directory without following symbolic links. Desktop mode is not affected.
This issue affects pgAdmin 4: before 9.19.
