An unauthenticated client that can reach a MongoDB Connector for BI deployment configured with Kerberos authentication may cause mongosqld to terminate when a crafted authentication exchange encounters a specific GSSAPI error-handling condition. This can interrupt BI Connector availability until the process restarts.

In MongoDB Connector for BI, mongodrdl may write a TLS private-key password to standard error when the password is supplied through both the connection URI and the corresponding command-line option. A local user with access to the captured command output and encrypted key file may use the disclosed password to access the associated TLS client key.
