What is CVE-2025-9897?

The AP Background plugin for WordPress has a vulnerability that exposes users to Cross-Site Request Forgery due to improper nonce validation in the advParallaxBackAdminSaveSlider function. Without proper nonce validation, unauthenticated attackers can potentially trick site administrators into executing unintended actions, such as creating or altering background sliders, by forging requests. To mitigate this risk, it’s essential to ensure that all relevant plugins are updated to their latest versions and that proper security measures are in place.
