CVE-2026-16296 in Clearfy Cache Plugin

Summary

by MITRE • 08/04/2026

The Clearfy Cache WordPress plugin before 2.4.3 does not validate the redirect target in its Cyrlitera old-URL redirect handler, passing a decoded request URI to an unsafe redirect function, which allows unauthenticated attackers to redirect visitors to an arbitrary external URL when a non-default option is enabled.
