What is CVE-2026-16042?
The LWS Optimize plugin for WordPress prior to version 3.4 contains a vulnerability that fails to implement proper capability checks on cache-clearing actions. This oversight enables authenticated users, including those with a Subscriber role, to clear the site's caches at will. As a result, it poses a risk of unauthorized cache manipulation, leading to potential disruption of service and performance issues due to repeated cache rebuilds.
Affected Version(s)
