LubeLogger is a self-hosted, open-source, web-based vehicle maintenance and fuel mileage tracker. Prior to 1.6.8, an authenticated user could submit caller-controlled recordIds to the DuplicateRecordsToOtherVehicles endpoint while naming destination vehicleIds the user could edit. The endpoint authorized the destination vehicles but fetched source records in Controllers/VehicleController.cs without checking UserCanEditVehicle for each existingRecord.VehicleId. This missing source-vehicle authorization allowed service, collision, upgrade, fuel, tax, supply, note, odometer, reminder, plan, inspection, and equipment records belonging to another user to be copied into an attacker-controlled vehicle, exposing record contents and attachment paths and creating persistent copies. This issue is fixed in version 1.6.8.
