Go to dashboardThe MongoDB C# Driver writes GeoJSON extra members without checking whether their names clash with reserved members such as type and coordinates. An application that uses user-supplied field names there can store documents with duplicate geometry fields, so the server and driver read different values and records can become unreadable through the driver.
Summary written from the sources below. Check the originals before acting.

Applications using the MongoDB C# Driver that place user-supplied field names into GeoJSON extra members. Applications that only write fixed GeoJSON geometry, or that do not accept user input into those members, are unlikely to be exposed; the sources do not name affected driver versions.

The MongoDB C# Driver writes GeoJSON extra members without checking whether their names collide with reserved GeoJSON members such as type and coordinates. An application that places user-supplied field names into these extra members can store documents with duplicate geometry fields, so the server and the driver resolve different values for the same record. Affected records can also become unreadable through the driver, interrupting application code that reads them.
