Okay, I get the adding of users, that makes sense. I can also see how they could get hashed passwords from an authors list.

But I still don't see how you could use SQL injection to get hashed passwords from the posts list unless it was an extremely complex SQL query combine with a really wide open hole, or if if the plugin already added a join to the users table.  To get hashed passwords the injection would have to modify the field list, and the table list, no? The field list is easy for a poorly coded plugin, but I don't see how it's likely to annotate a join to the table list via SQL injection?  If it is possible, please inform me how so I can make sure to never allow it in my plugins.
