Vertical scroll recent post <= 14.0 - Cross-Site Request Forgery via vsrp_admin_options

Description

The Vertical scroll recent post plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 14.0. This is due to missing or incorrect nonce validation on the 'vsrp_admin_options' 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.
