## Description

The bbPress plugin for WordPress is vulnerable to Sensitive Information Exposure via attachment pages, canonical redirects and oEmbed lookups in all versions up to, and including, 2.6.19, due to missing checks on the visibility of an attachment's parent forum, topic or reply. Topics and replies in private or hidden forums keep a public post status, so WordPress treats media attached to them as public. This makes it possible for unauthenticated attackers to view attachment pages and media URLs of files attached to topics and replies in private or hidden forums, or to password-protected content.
