+    graph [goal="UsernameValidator allows trailing newline in usernames
+Description
+	
+ASCIIUsernameValidator and UnicodeUsernameValidator use the regex 
+r'^[\w.@+-]+$'
+The intent is to only allow alphanumeric characters as well as ., @, +, and -. However, a little known quirk of Python regexes is that $ will also match a trailing newline. Therefore, the user name validators will accept usernames which end with a newline. You can avoid this behavior by instead using \A and \Z to terminate regexes. For example, the validator regex could be changed to
+r'\A[\w.@+-]+\Z'
+in order to reject usernames that end with a newline.
+I am not sure how to officially post a patch, but the required change is trivial - using the regex above in the two validators in contrib.auth.validators.
