CVE-2026-27603 | THREATINT

Description

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to version 4.8.4, the chart filter endpoint POST /project/:project_id/chart/:chart_id/filter is missing both verifyToken and checkPermissions middleware, allowing unauthenticated users to access chart data from any team/project. This issue has been patched in version 4.8.4.
