CVE-2026-59780Network attack vector

LDAP configuration disclosure via unrestricted provider listing

Published Aug 21, 2026 · Updated Aug 21, 2026

LDAP disclosure in Apache CloudStack 4.2.0.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0 allows remote authenticated users to list LDAP servers. The listLdapConfigurations API returns configured LDAP hostnames, ports, and linked domains without restricting the call to privileged roles. Any authenticated account in a default role can invoke the API, exposing directory-service topology but not LDAP credentials.
