Summary
An unauthenticated client can query the Security Domain hosts inventory via GET /ca/rest/securityDomain/hosts and receive a structured response enumerating internal PKI/CA hosts and roles (security domain topology and participating subsystems), without requiring a principal, client certificate, or session.
Rated Moderate because this is unauthenticated disclosure of internal host and topology metadata only; the disclosed hostnames and roles do not directly expose credentials or sensitive data, making this a reconnaissance/follow-on-attack enabler rather than a direct compromise.
Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). Affected Red Hat products: Red Hat Certificate System 9; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat does not currently list a fixing RHSA for this CVE.
