NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo as a user not present in the local password database is an intentional feature. Because this behavior surprised some users sudo 1.8.30 introduced an option to enable/disable this behavior with the default being disabled. However this does not change the fact that sudo was behaving as intended and as documented in earlier versions.
