## Technical details

The MaintenanceEntryRepository.Update and MaintenanceEntryRepository.Delete methods in the backend lack group membership verification, using only the entry ID without confirming the authenticated user belongs to the owning group. An authenticated attacker can invoke these operations over the network with a known or brute-forced maintenance entry UUID to overwrite or delete arbitrary records. This is fixed in version 0.26.0.
