Smart Online Order for Clover < 1.5.5 - Cross-Site Request Forgery

Description

The Smart Online Order for Clover plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.4. This is due to missing or incorrect nonce validation on the page_coupons() function. This makes it possible for unauthenticated attackers to create arbitrary coupons via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
