CVE-2021-31930
Persistent cross-site scripting (XSS) in the web interface of Concerto through 2.3.6 allows an unauthenticated remote attacker to introduce arbitrary JavaScript by injecting an XSS payload into the First Name or Last Name parameter upon registration.
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
