Multiple vulnerabilities have been discovered in the Mingle Forum plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.
1) Input passed to the "groupid" parameter in wp-admin/admin.php (when "page" is set to "mfstructure", "mingleforum_action" is set to "structure", and "do" is set to "editgroup") and "usergroup_id" parameter in wp-admin/admin.php (when "page" is set to "mfgroups", "mingleforum_action" is set to "usergroups", and "do" is set to "edit_usergroup") is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed to the "forumid" parameter in wp-admin/admin.php (when "page" is set to "mfstructure", "mingleforum_action" is set to "structure", and "do" is set to "editforum") is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerabilities are confirmed in version 1.0.33. Other versions may also be affected.
