WP Database Reset < 3.1 - Unauthenticated Database Table Reset via admin-post.php
The WordPress plugin, WP Database Reset through 3.1, contains a flaw that allowed any unauthenticated user to reset any table in the database to the initial WordPress set-up state (deleting all site content stored in that table), as demonstrated by a wp-admin/admin-post.php?db-reset-tables[]=comments URI.
