Description

The Core Web Vitals & PageSpeed Booster plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 1.0.12. This is due to insufficient validation on the redirect url supplied via the _wp_http_referer parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.
