A flaw in the connection management layer of the MongoDB Node.js driver can leave a pooled network connection in the pool for reuse while data from an earlier operation is still outstanding on it.

This may result in unintended disclosure of other users' records, incorrect operation results being returned, and failures of legitimate requests.
