OpenHealth through 0.2.0 contains a missing authentication and authorization vulnerability in the /api/health-data/[id] GET, PATCH and DELETE handlers that query records by id without session or authorId checks. Unauthenticated attackers who know a HealthData record id can read another user's medical record data and file metadata, overwrite it with arbitrary JSON, or delete it.
