Icegram < 3.1.19 - Cross-Site Request Forgery via save_campaign_preview

Description The Icegram plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.1.18. This is due to missing or incorrect nonce validation on the save_campaign_preview() function. This makes it possible for unauthenticated attackers to save campaign previews via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
