Summary
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, allowing unauthenticated attackers to create or modify background sliders via a forged request if they can trick a site administrator into clicking a link.
Risk Assessment
An attacker could exploit CSRF to unauthorizedly modify plugin settings, potentially leading to site defacement or injection of malicious content.
Recommendation
Update the AP Background plugin to the latest version that includes a fix adding nonce validation.
