Summary

The NGINX Cache Optimizer plugin for WordPress (all versions up to and including 1.1) is vulnerable to unauthorized modification of data due to a missing capability check on the 'nginxcacheoptimizer-blacklist-update' AJAX action. An authenticated attacker with Subscriber-level access or higher can add URLs to the Exclude URLs From Dynamic Caching setting.

Risk Assessment

An attacker with low privileges can modify the dynamic caching exclusion configuration, potentially leading to improper cache behavior and consequently data exposure or performance issues. The risk affects all sites with the vulnerable plugin version installed.

Update the NGINX Cache Optimizer plugin to the latest version (above 1.1) or remove it if not used. Additionally, verifying user permissions and regularly reviewing plugin settings is recommended.
