The published events may contain security-sensitive data when commands such as \"saslStart\", \"saslContinue\", \"isMaster\", \"createUser\", and \"updateUser\" are executed. Without due care, an application may inadvertently expose this authenticated-related information, e.g., by writing it to a log file. This issue only arises if an application enables the command listener feature (this is not enabled by default). This issue affects the MongoDB C# Driver v2.12 versions prior to and including 2.12.1.\n\n\n\n\n"
