Research Description: The USS Upyun plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.0. This is due to missing or incorrect nonce validation on the uss_setting_page function when processing the uss_set form type.

Affected versions: max 1.5.1.
