What the vulnerability does
The AP Background plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.8.2. This is due to missing or incorrect nonce validation on the advParallaxBackAdminSaveSlider function. This makes it possible for unauthenticated attackers to create or modify background sliders via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without the administrator's knowledge or consent. The vulnerability requires the administrator to visit the attacker's page while authenticated.
What an attacker can do
Perform unwanted actions on the site by tricking an authenticated administrator into visiting a malicious webpage.
Potential impact on your site
