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.

Closes: 1145669 1145816
Changes:
keystone (2:27.0.0-3+deb13u5) trixie-security; urgency=medium
.
* CVE-2026-80184: Delegation bypass in trust, OAuth1, and application
credential operations.
* CVE-2026-80182: Tokens obtained via application credential or EC2
credential authentication can escape their intended project scope through
token-method reauthentication. An application-credential token scoped to
one project can be exchanged via POST /v3/auth/tokens with no explicit
scope, causing Keystone to issue a new token scoped to the owner's default
project. For EC2-derived tokens the bypass is broader: because they carry
no delegation markers, they can rescope to any project where the underlying
user has role assignments.
* Add new patches (Closes: #1145669):
- CVE-2026-80182_CVE-2026-80184_1_Block_app_credential_token_resco....patch
- CVE-2026-80182_CVE-2026-80184_2_auth_encode_ec2credential_and_oa....patch
- CVE-2026-80182_CVE-2026-80184_3_trusts_oauth1_app-creds_reject_d....patch
- CVE-2026-80182_CVE-2026-80184_4_auth_reject_delegated_tokens_fro....patch
* 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.
Applied upstream patch (Closes: #1145816):
- CVE-2026-80183_Prevent_unauthorized_project-scoped_assignment_list.patch
