I recently committed the following change to the Development Version of FeedWordPress:

IMPORTANT SECURITY FIX. / Ver bump. Important security fix for potential WordPress security vulnerability across several plugins discussed at ​https://blog.sucuri.net/2015/04/security-advisory-xss-vulnerability-affecting-multiple-wordpress-plugins.html . Props to ​http://github.com/quassy/

This change will be part of the next public release of FeedWordPress. Interested? Curious? You can check out the details at the WordPress plugin repository ...
