Youtube SpeedLoad <= 0.6.3 - Cross-Site Request Forgery

Description

The Youtube SpeedLoad plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 0.6.3. This is due to missing or incorrect nonce validation on the ytsl_settings_page() function. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
