Security question

I am fairly new to Linux so I have been reading "A Practical Guide to Linux
Commands, Editors and Shell Programming",  In the book they say that it is a
security issue to place the working directory and/or the home directory at the
front of the PATH.  Is this true?  If it is why does Ubuntu put the home
directory first in the PATH?
