I believe this is the same for all versions of phpslash since 0.62 up to 
0.72rc1:

1. Go to the Admin section
2. Hit "new" to add a new story
3. Try to add a story that contains Perl code with hashes defined like: 
$myhas{td} . etc...

The {td} part of the hashes will mess up the article badly when previewing. 
In fact, the whole page gets mumble with all kinds of crazy things. What I 
do to fix that is adding spaces between the curly-braces.

I don't think this affects the server directly, nor have I try to inject any 
type of code to the database. In other words, I'm assuming this cannot be 
done and have not tried. In any case, only the users with Admin rights can 
add news to the site. So, nothing to worry (right?).

However, I believe that the stories (the text coming from the database to be 
displayed as stories) should not be parse as if it was a template or as if 
dynamic PHP code was coming from the database... That could create problems. 
(It creates problems for people who have sites publishing code, as I do :-) 
)
