CVE-2021-37573
A reflected cross-site scripting (XSS) vulnerability in the web server TTiny Java Web Server and Servlet Container (TJWS) <=1.115 allows an adversary to inject malicious code on the server's "404 Page not Found" error page
Does this matter?
Lower severity and a low EPSS score (3.40%). Track it; it rarely justifies an emergency change on its own.
