CVE-2021-24574
The Simple Banner WordPress plugin before 2.10.4 does not sanitise and escape one of its settings, allowing high privilege users such as admin to use Cross-Site Scripting payload even when the unfiltered_html capability is disallowed.
Does this matter?
Lower severity and a low EPSS score (0.68%). Track it; it rarely justifies an emergency change on its own.
