Hi, The following vulnerability was published for keystone. CVE-2026-80183[0]: | In OpenStack Keystone before 29.0.3, any authenticated user holding | role:reader on any project can list every project-scoped role | assignment under any domain by passing a domain ID as | scope.project.id with include_subtree to the GET | /v3/role_assignments endpoint. The domain's project record has | domain_id=null, causing the policy domain_id check to pass for any | caller. With include_names, the response discloses the names and | home-domain IDs of every user, group, project, and role involved. | The literal "default" domain ID works against any deployment created | with keystone-manage bootstrap. An attacker can harvest domain IDs | from the response and repeat the query to map role assignments | across the entire cloud. This is caused by misuse of "None" in | list_role_assignments_for_tree. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry. For further information see: [0] https://security-tracker.debian.org/tracker/CVE-2026-80183 https://www.cve.org/CVERecord?id=CVE-2026-80183 [1] https://launchpad.net/bugs/2154645 Please adjust the affected versions in the BTS as needed.

* CVE-2026-80183 / OSSN-2026-0XXX: any authenticated user holding role:reader
on any project can list every project-scoped role assignment under any
domain by passing a domain ID as scope.project.id with include_subtree to
the GET /v3/role_assignments endpoint. The domain's project record has
domain_id=null, causing the policy domain_id check to pass for any caller.
With include_names, the response discloses the names and home-domain IDs of
every user, group, project, and role involved. The literal "default" domain
ID works against any deployment created with keystone-manage bootstrap. An
attacker can harvest domain IDs from the response and repeat the query to
map role assignments across the entire cloud. This is caused by misuse of
"None" in list_role_assignments_for_tree.
