Overview

CVE-2026-40595 is a high-severity vulnerability. It was published on April 30, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
