Auth bypass in Chartbrew

CVE-2026-32252

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 4.9.0, a cross-tenant authorization bypass exists in Chartbrew in GET /team/:team_id/template/generate/:project_id. The GET handler calls checkAccess(req, "updateAny", "chart") without awaiting the returned promise, and it does not verify that the supplied project_id belongs to req.params.team_id or to the caller's team. As a result, an authenticated attacker with valid template-generation permissions in their own team can request the template model for a project belonging to another team and receive victim project data. This vulnerability is fixed in 4.9.0.
