Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

CloudBeaver 是一款云数据库管理工具。在 26.1.1 及更早版本中，部分服务器端导出操作未能始终强制执行全局数据导出限制。拥有共享数据库连接权限的已认证非管理员用户，即使管理员已禁用导出功能，仍可触发某些服务器端数据导出操作。这可能导致披露该用户被允许查询但未被允许导出的数据库内容。该问题不会赋予额外的数据库读取权限。此问题已在 26.1.2 版本中修复，通过始终对服务器端导出操作强制执行全局限制来解决问题。

Vulnerability Title

CloudBeaver: Authorization Bypass (BFLA) - Data Export Restriction Bypass

Source: CVE Program / CVE List V5

Vulnerability Description

CloudBeaver is a cloud database manager. In versions up to and including 26.1.1, some server-side export operations do not consistently enforce the global data export restriction. An authenticated non-administrative user with access to a shared database connection can initiate certain server-side data exports even when an administrator has disabled exports. This can disclose database contents that the user is permitted to query but is not permitted to export. The issue does not grant additional database read privileges. It is fixed in 26.1.2 by consistently enforcing the global restriction for server-side exports.
