[Plugin: Cross-linker] CSRF security issue?

Hello,

I think there is a small CSRF security issue in line 774:

if($_REQUEST[‘del_word’]!=”)
{
$del_me = $_REQUEST[‘del_word’];
$wpdb->query(“DELETE FROM $table_name WHERE id = ‘”.$del_me.”‘;”);
$table_name_attrs = $wpdb->prefix . $table_crosslink_attrb;
$wpdb->query(“DELETE FROM $table_name_attrs WHERE id = ‘”.$del_me.”‘;”);
}

An attacker could trick a logged in Cross-Linker user into deleting all hyperlinked words.

To fix, add

check_admin_referer();

before

$del_me = $_REQUEST[‘del_word’];

Have fun
