Avoiding code injections with c# Driver for MongoDB

Question

I have the following code that checks if a user-entered email already exists in the collection:

MongoDatabase authdb = DatabaseManager.GetDatabase("authdb");
var userDocuments = authdb.GetCollection<UserDocument>(UserDocument.CollectionName);
var doc = userDocuments.FindOne(new QueryDocument("email", email));

I'm a little that using a value (email) supplied by user is opening an opportunity for sorts of injections, kind of like SQL injection. Is it a real problem and how to approach it then?

Official docs are here.
