The bbPress plugin for WordPress allows for topics and replies to be entered by otherwise untrusted sources. As such, it's important that all data that's stored in the DB is properly escaped, sanitized, and checked for potential unauthorized use. Much of this is done already, and much of it is internally handled by WordPress. Still, it deserves a closer look to be sure we're avoiding potential dangers.
