Description
OpenPanel before 3.0.0 contains a missing authorization vulnerability that allows unauthenticated attackers to read any project's annotations by calling the public reference.getChartReferences tRPC procedure. Attackers can send requests with guessable slug-based project IDs to dump cross-tenant annotation titles, descriptions, and dates such as release notes and deploy markers.
