CVE-2021-24481
The Any Hostname WordPress plugin through 1.0.6 does not sanitise or escape its "Allowed hosts" setting, leading to an authenticated stored XSS issue as high privilege users are able to set XSS payloads in it
Does this matter?
Lower severity and a low EPSS score (0.61%). Track it; it rarely justifies an emergency change on its own.
