5DescriptionGitHub Advisory
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.
AnalysisAI
Chartbrew 4.9.0 fails to properly enforce project-level access controls on a legacy dashboard route, allowing any authenticated team member to read another team member's project report data and extract stored report passwords. The vulnerability affects users without explicit project access but with team membership, who can leverage the unprotected endpoint to view sensitive dashboard configurations and credentials. Patched in version 5.0.0.
Technical ContextAI
Chartbrew is an open-source data visualization platform that connects to databases and APIs to generate charts and dashboards. The vulnerability exists in a legacy API endpoint responsible for serving project dashboard data. The root cause is an authorization bypass (CWE-284: Improper Access Control) where the endpoint validates team membership but fails to verify project-level permissions. The endpoint returns the raw project object including sensitive fields such as stored report passwords. This is a common pattern in multi-tenant applications where endpoint-level access control neglects to implement role-based access control (RBAC) at the resource level, allowing horizontal privilege escalation within a team scope.
RemediationAI
Upgrade Chartbrew immediately to version 5.0.0 or later, which includes the authorization control patch. The upgrade path is straightforward for v4 users and does not require manual migration. If immediate upgrade is not feasible, restrict network access to the Chartbrew application to trusted internal users only, or implement reverse-proxy authentication requiring explicit project membership verification at the network layer. However, these workarounds do not address the underlying authorization flaw and should be considered temporary only. Monitor access logs for suspicious cross-project requests from low-privileged team members.
