X-Debbugs-Cc: OSSA-2026-037: Inconsistent scope enforcement for delegated
tokens in Keystone, Debian Security Team <[email protected]>
As per upstream announce at:
https://security.openstack.org/ossa/OSSA-2026-037.html
Date: August 25, 2026
CVE: CVE-2026-80182, CVE-2026-80184
Affects: Keystone: >=13.0.0 <27.0.3, >=28.0.0 <28.0.3, >=29.0.0 <29.0.3
Description:
Grzegorz Grasza (Red Hat) reported that OpenStack Keystone did not consistently
block delegated tokens from creating new long-lived credentials or authorizing
new delegations. Tim Shephard (roiai.ca) separately reported that delegated
tokens could be submitted to the token-method authentication path to escape
their project scope.
A token scoped through an OAuth1 access token, an application credential, or a
trust could create new long-lived credentials or authorize new delegations
that persist independently of, and outlive, the credential used to obtain
them. Separately, tokens obtained through any of these delegation mechanisms
could be submitted to the token-method authentication path for
reauthentication. When an application credential token was presented with no
explicit scope, Keystone would issue a new token scoped to the credential
owner’s default project rather than the project for which the credential was
issued, escaping the intended project boundary.
All Keystone deployments that permit delegated authentication through OAuth1
access tokens, application credentials, or trusts are affected.
Errata:
CVE-2026-80182 and CVE-2026-80184 have been assigned for these vulnerabilities.

Notes:
The two patch sets are interdependent and must be applied together. The
token reauthentication guard introduced by the second patch depends on the
delegation classification logic and the new [auth]
additional_primary_auth_methods configuration option introduced by the first.
Packaging or applying a subset is not supported.
After upgrading, Keystone treats any authentication method not built in
to Keystone as a delegated credential and rejects it from guarded operations
(managing trusts, application credentials, and OAuth1 access tokens, and
token reauthentication). Deployments running a custom or third-party
authentication plugin must add it to [auth] additional_primary_auth_methods
or those authentication flows will fail.
This advisory does not address a related weakness in EC2 credential
(ec2credential) handling, which is being tracked and fixed in public and
will be covered by a separate OpenStack Security Note (OSSN).
A related fix to the Keystone Tempest plugin test suite was proposed
at https://review.opendev.org/1002296
