Summary

The report.get procedure in packages/trpc/src/routers/report.ts accepted only a reportId and returned getReportById(reportId) directly. The enforceAccess middleware in packages/trpc/src/trpc.ts evaluates membership only when the input carries a projectId or organizationId key, so an input consisting of a reportId alone passed through unchecked, and getReportById in packages/db/src/services/reports.service.ts performs a findUnique on the report id with no project scoping. Any authenticated user could therefore read the full configuration of any saved report on the instance, including the owning projectId, event series, filters, breakdowns and formulas, by supplying its identifier. The adjacent update, delete and duplicate procedures resolve the report first and check getProjectAccess against the report's own projectId, so the omission was specific to this procedure.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of Openpanel-dev/openpanel published their own advisory on GitHub. Reviewed sources take precedence over it.
