CVE-2020-5541
Open redirect vulnerability in CyberMail Ver.6.x and Ver.7.x allows remote attackers to redirect users to arbitrary sites and conduct phishing attacks via a specially crafted URL.
Does this matter?
Lower severity and a low EPSS score (1.39%). Track it; it rarely justifies an emergency change on its own.
