CVE-2026-80183Network attack vectorHinoki check available

Cross-domain role disclosure via null scope comparison

Published Aug 26, 2026 · Updated Aug 27, 2026

Type confusion in affected OpenStack Keystone releases before 29.0.3 allows remote authenticated users to disclose cross-domain role assignments. list_role_assignments_for_tree treats a domain project whose domain_id is null as matching the caller's project-domain policy target. A reader role on any project and a domain ID are sufficient; include_names exposes the involved users, groups, projects, roles, and home-domain IDs.
