CVE-2020-2187
Jenkins Amazon EC2 Plugin 1.50.1 and earlier unconditionally accepts self-signed certificates and does not perform hostname validation, enabling man-in-the-middle attacks.
Does this matter?
Lower severity and a low EPSS score (0.41%). Track it; it rarely justifies an emergency change on its own.
