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 a legacy dashboard route that returns a project's report data to any authenticated member of the same team, even when that user does not have access to the specific project. The route bypasses project-level authorization and returns the raw project object. As a result, a low-privileged same-team user can read another project's dashboard data and recover the project's stored report password from the response. This issue has been patched in version 5.0.0.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
