CVE-2018-9186
A cross-site scripting (XSS) vulnerability in Fortinet FortiAuthenticator in versions 4.0.0 to before 5.3.0 "CSRF validation failure" page allows attacker to execute unauthorized script code via inject malicious scripts in HTTP referer header.
Does this matter?
Lower severity and a low EPSS score (0.73%). Track it; it rarely justifies an emergency change on its own.
