An incorrect authorization check in the MongoDB Server authorization subsystem may allow an unauthenticated party with local host access to obtain administrative privileges on a database server that has authorization enabled. This may result in unintended access to stored data and credentials, unintended modification of data, and loss of availability of the server.
