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.

The Watu Quiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'watu-basic-chart' shortcode in all versions up to, and including, 3.4.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Watu Quiz plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.4.1 via the watu-userinfo shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to extract sensitive user meta data which can include session tokens and user emails.
