Description
It seems that it is possible to update illegal top level fields ($ref, $id, $db). Note that this fails if you use insert, instead of update.
> db.test.drop()
|
true
|
> db.test.update({_id:0}, {_id:0, $ref: "1", $id: 1, $db:"1"}, true)
|
WriteResult({ "nMatched" : 0, "nUpserted" : 1, "nModified" : 0, "_id" : 0 })
|
> db.test.findOne()
|
{ "_id" : 0, "$ref" : "1", "$id" : 1, "$db" : "1" }
|
> db.test.insert({_id: 1, $ref: "1", $id: 1, $db: "1"})
|
WriteResult({
|
"nInserted" : 0,
|
"writeError" : {
|
"code" : 2,
|
"errmsg" : "Document can't have $ prefixed field names: $ref"

}

})
|
> db.test.find()
|
{ "_id" : 0, "$ref" : "1", "$id" : 1, "$db" : "1" }

> db.runCommand({buildinfo:1})
