An improper neutralization of input during web page generation in FortiAuthenticator WEB UI 6.0.0 may allow an unauthenticated user to perform a cross-site scripting attack (XSS) via a parameter of the logon page.
Does this matter?
Lower severity and a low EPSS score (0.70%). Track it; it rarely justifies an emergency change on its own.
