The bbPress plugin through 2.6.4 for WordPress has stored XSS in the Forum creation section, resulting in JavaScript execution at wp-admin/edit.php?post_type=forum (aka the Forum listing page) for all users. An administrator can exploit this at the wp-admin/post.php?action=edit URI.
bbPress 1.0.2 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by bb-templates/kakumei/view.php and certain other files.
Cross-site scripting (XSS) vulnerability in bb-login.php in bbPress 0.8.1 allows remote attackers to inject arbitrary web script or HTML via the re parameter. NOTE: exploitation may require forcing the client to send a certain Referer header.
SQL injection vulnerability in bb-includes/formatting-functions.php in bbPress before 0.8.1 might allow remote attackers to execute arbitrary SQL commands via unspecified vectors to forums/bb-edit.php, as demonstrated by a PRE element, aka the "quircky slashes bug."
