## Description

The bbPress plugin for WordPress is vulnerable to unauthorized content creation in all versions up to, and including, 2.6.19 due to a missing password-required check in the new topic and new reply handlers. This makes it possible for authenticated attackers, with Subscriber-level access and above, to post new topics and replies into password-protected forums or topics without supplying the password.
