The report.list procedure in packages/trpc/src/routers/report.ts accepted a projectId and a dashboardId and returned getReportsByDashboardId(dashboardId). The enforceAccess middleware in packages/trpc/src/trpc.ts verified membership for the supplied projectId, but nothing verified that the supplied dashboardId belonged to that project, and getReportsByDashboardId in packages/db/src/services/reports.service.ts selects reports by dashboardId alone with no project scoping. An authenticated user could therefore pair a projectId from their own organization, which satisfies the middleware, with a dashboardId belonging to another organization and receive every report in that dashboard. A correctly scoped helper, listReportsCore, already existed in the same service file and resolves the dashboard through getDashboardById(dashboardId, projectId) before returning reports, but the router did not use it.
