Description
HomeBox is a home inventory and organization system. Prior to 0.26.0, MaintenanceEntryRepository.Update and MaintenanceEntryRepository.Delete in backend/internal/data/repo/repo_maintenance_entry.go use UpdateOneID(id) and DeleteOneID(id) without verifying that the maintenance entry belongs to the authenticated user's active group. An authenticated low-privileged user who knows or enumerates another tenant's maintenance-entry UUID can overwrite that record or permanently delete it. This issue is fixed in version 0.26.0.
