In some applications this may result in clients being able cause effects that would otherwise not be allowed.

The new behaviour is to have an empty ACL file mean that all access is denied, which is not a useful configuration but is not unexpected.

This typically means that the malformed data becomes a username and no password. If this occurs, clients can circumvent authentication and get access to the broker by using the malformed username. In particular, a blank line will be treated as a valid empty username. Other security measures are unaffected. Users who have only used the mosquitto_passwd utility to create and modify their password files are unaffected by this vulnerability.
