Posti Shipping < 3.10.4 - Cross-Site Request Forgery

Description

The Posti Shipping plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.10.3. This is due to missing or incorrect nonce validation on several functions. This makes it possible for unauthenticated attackers to change plugin settins via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
