What is CVE-2026-53682?

A security vulnerability allows unauthenticated users to access sensitive information related to the Security Domain's internal hosts. By querying the endpoint /ca/rest/securityDomain/hosts, an attacker can obtain a detailed inventory of PKI and CA hosts, along with their associated roles within the security topology. This unauthorized access does not require a principal, client certificate, or session, potentially exposing critical infrastructure details and increasing the risk of further attacks.
