CVE-2026-40904— Chartbrew: Incorrect Access Control in dataset and dataRequest routes via team-scoped permission checks

Chartbrew: Incorrect Access Control in dataset and dataRequest routes via team-scoped permission checks

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. In version 4.9.0, Chartbrew exposes multiple dataset and dataRequest endpoints that authorize low-privileged project members at the team level instead of binding the requested dataset_id, dataRequest id, and connection_id to the caller's allowed projects. An authenticated attacker who only has access to one project inside a team can read, execute, create, update, and delete datasets and data requests that belong to other projects in the same team. The issue is exploitable remotely with ordinary project-level credentials and leads to cross-project data disclosure and unauthorized use of victim-side database or API connections. This issue has been patched in version 5.0.0.

访问控制不恰当

chartbrew 访问控制错误漏洞

chartbrew是Chartbrew开源的一个数据可视化与仪表盘构建工具。 Chartbrew 4.9.0版本存在访问控制错误漏洞，该漏洞源于多个数据集和数据请求端点仅按团队级别授权低权限项目成员，未将请求的dataset_id、dataRequest id和connection_id绑定到调用者的允许项目，可能导致认证攻击者跨项目读取、执行、创建、更新和删除数据集及数据请求。
