CloudBeaver 是一款云数据库管理工具。在从 2.2.3 到 26.1.2 的版本中，其 SQL 结果编辑功能存在路径遍历漏洞：拥有 SQL 结果编辑权限的已认证用户可诱导服务器打开位于预期临时上传目录之外的文件。在受影响的数据库值处理场景中，该漏洞可能导致 CloudBeaver 服务器进程可读的本地文件被泄露。版本 26.1.2 已修复此问题，阻止了超出预期临时上传目录的路径遍历行为。

CloudBeaver: Path Traversal in updateResultsDataBatch Allows Unauthorized Server File Stream Access
Source: CVE Program / CVE List V5
Vulnerability Description
CloudBeaver is a cloud database manager. From version 23.2.3 until 26.1.2, a path traversal vulnerability in its SQL result-editing functionality allows an authenticated user with SQL result-editing privileges to cause the server to open files outside the intended temporary upload directory. In affected database value-handling scenarios, this can disclose local files readable by the CloudBeaver server process. Version 26.1.2 prevents traversal outside the intended temporary upload directory.
