What the vulnerability does
The NGINX Cache Optimizer plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'nginxcacheoptimizer-blacklist-update' AJAX action in all versions up to, and including, 1.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to add URLs to the Exclude URLs From Dynamic Caching setting.
Explanation of Vulnerability in Simple Terms
NGINX Cache Optimizer versions 1.1 and earlier lack proper authorization checks, allowing authenticated users to modify cache settings they should not have access to. An attacker with low-privilege account access can alter caching behavior, potentially affecting site performance or exposing cached content. Update to a version newer than 1.1 to remediate.
What an attacker can do
Modify cache settings or behavior without proper authorization.
Potential impact on your site
Unauthorized users can alter cache configuration, potentially degrading performance or exposing sensitive cached data.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site.
