CVE-2020-28053
HashiCorp Consul and Consul Enterprise 1.2.0 up to 1.8.5 allowed operators with operator:read ACL permissions to read the Connect CA private key configuration.
Does this matter?
Lower severity and a low EPSS score (1.45%). Track it; it rarely justifies an emergency change on its own.
