CVE-2020-12714
A Diffie-Hellman parameter of insufficient size could allow man-in-the-middle compromise of communications between CipherMail products and external SMTP clients.
Does this matter?
Lower severity and a low EPSS score (0.97%). Track it; it rarely justifies an emergency change on its own.
