hostel <= 1.1.5.3 - Cross-Site Request Forgery

The Hostel plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.5.3. This is due to missing or incorrect nonce validation when managing rooms. This makes it possible for unauthenticated attackers to create and delete rooms via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
