CWE is classifying the issue as CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. This is going to have an impact on confidentiality. The summary by CVE is:

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.
