Description
The bbPress plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.6.18. The topic and reply content functions, feeds and REST read checks honor only a post's own password, not a password set on its parent forum or topic. This makes it possible for unauthenticated attackers to read topics and replies inside password-protected forums, and replies inside password-protected topics, by opening their permalinks or feeds directly without knowing the password.
