CVE-2026-40595 Details
Description
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 public chart retrieval and export routes that only verify project-level public access and, for exports, a team-level export toggle. The routes do not verify whether the target chart is actually allowed on the public report or whether the governing SharePolicy permits public access. An unauthenticated attacker who knows a chart identifier in a public project can read or export chart data for charts that were intentionally hidden from the report. This issue has been patched in version 5.0.0.
A vulnerability in Chartbrew version 4.9.0 allows unauthenticated access to chart data that is intentionally hidden from public reports. The issue arises because the public chart retrieval and export routes only verify project-level public access and, for exports, a team-level export toggle. They do not check if the chart is allowed on the public report or if the governing SharePolicy permits public access. As a result, an attacker who knows a chart identifier in a public project can read or export data from charts that were meant to be private.
Users are advised to update to Chartbrew version 5.0.0, where this vulnerability has been patched.
