Description¶

For more information, see Specifying Account Names.

The host name part of an account name can take many forms, and wildcards are permitted:

Because IP wildcard values are permitted in host values (for example, ‘198.51.100.%’ to match every host on a subnet), someone could try to exploit this capability by naming a host 198.51.100.somewhere.com. To foil such attempts, MySQL does not perform matching on host names that start with digits and a dot. For example, if a host is named 1.2.example.com, its name never matches the host part of account names. An IP wildcard value can match only IP addresses, not host names.
For a host value specified as an IPv4 address, a netmask can be given to indicate how many address bits to use for the network number. Netmask notation cannot be used for IPv6 addresses.

Remove any user that does not have a name in the mysql.user table. Or change the host to something with a limited scope.
