Today, I just register myself for a free wordpress blogging. I was adding categories when this error poped up.
Database error: [Duplicate entry 'Mood' for key 2]
INSERT INTO wp_geek_categories (cat_ID, cat_name, category_nicename, category_description, category_parent) VALUES ('0', 'Mood', 'mood', '', '0')
Yes, I was aware enough when I click the add category button for the secon d time (the update seemd to be hung for my connection is walking lke a slug) but I didn't expect that wordpress would spit out that dangerous SQL information. WordPress reveal its own database schema. Yummy, I wonder I could SQL inject it somewhere .. maybe the login stuff. This is just like that IPB, spitting out clear SQL error.
This service I use is using WordPress 1.2
