Lws Optimize
Monthly
Cache management actions in the LWS Optimize WordPress plugin before version 3.4 lack authorization checks, permitting any authenticated user - including low-privileged Subscribers - to flush the site's caches and trigger repeated, resource-intensive cache rebuilds. The vulnerability is classified as CWE-862 (Missing Authorization) and carries a CVSS 3.1 score of 4.3 (Medium), with impact limited to availability degradation rather than data exposure or modification. A publicly available proof-of-concept exists per WPScan reporting, though EPSS sits at a very low 0.13% (3rd percentile) and the vulnerability is not listed in CISA KEV, indicating limited observed exploitation interest.
