{"id":"UBUNTU-CVE-2026-90460","details":"An issue was discovered in OpenStack Keystone before 29.0.3. Tokens obtained via delegated authentication methods (EC2 credentials, application credentials, OAuth1 access tokens, and trusts) are not blocked from creating, modifying, or deleting credentials via the /v3/credentials API. EC2-derived tokens can additionally read credential blobs, exposing TOTP MFA seeds and other secrets. Also, PATCH /v3/credentials does not validate the requested post-update project_id, allowing any delegated token to move a credential to an unauthorized project. All Keystone deployments using delegated authentication are affected.","modified":"2026-09-16T11:44:18Z","published":"2026-09-11T22:16:00Z","upstream":["CVE-2026-90460"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-90460"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-90460"},{"type":"REPORT","url":"https://bugs.launchpad.net/keystone/+bug/2159643"},{"type":"REPORT","url":"https://bugs.launchpad.net/keystone/+bug/2158931"},{"type":"REPORT","url":"https://review.opendev.org/c/openstack/keystone/+/1002330"},{"type":"REPORT","url":"https://launchpad.net/bugs/2158931"},{"type":"REPORT","url":"https://launchpad.net/bugs/2159643"},{"type":"REPORT","url":"https://review.opendev.org/1002330"}],"affected":[{"package":{"name":"keystone","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/keystone?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:8.0.0-0ubuntu1","2:9.0.0~b1-0ubuntu1","2:9.0.0~b2-0ubuntu1","2:9.0.0~b3-0ubuntu1","2:9.0.0~rc1-0ubuntu1","2:9.0.0-0ubuntu1","2:9.0.2-0ubuntu1","2:9.0.2-0ubuntu2","2:9.1.0-0ubuntu1","2:9.2.0-0ubuntu1","2:9.3.0-0ubuntu1","2:9.3.0-0ubuntu2","2:9.3.0-0ubuntu3","2:9.3.0-0ubuntu3.1","2:9.3.0-0ubuntu3.2"],"ecosystem_specific":{"binaries":[{"binary_name":"keystone","binary_version":"2:9.3.0-0ubuntu3.2"},{"binary_name":"python-keystone","binary_version":"2:9.3.0-0ubuntu3.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90460.json"}},{"package":{"name":"keystone","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/keystone?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:12.0.0-0ubuntu1","2:13.0.0~b1-0ubuntu1","2:13.0.0~b2-0ubuntu1","2:13.0.0~b3-0ubuntu1","2:13.0.0~rc1-0ubuntu1","2:13.0.0~rc2-0ubuntu1","2:13.0.0-0ubuntu1","2:13.0.1-0ubuntu1","2:13.0.2-0ubuntu1","2:13.0.2-0ubuntu3","2:13.0.4-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"keystone","binary_version":"2:13.0.4-0ubuntu1"},{"binary_version":"2:13.0.4-0ubuntu1","binary_name":"python-keystone"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90460.json"}},{"package":{"name":"keystone","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/keystone?arch=source&distro=esm-infra%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:16.0.0-0ubuntu1","2:17.0.0~b1~git2019121613.db81fee63-0ubuntu1","2:17.0.0~b2~git2020020513.99733f172-0ubuntu1","2:17.0.0~b3~git2020032415.9f9040257-0ubuntu1","2:17.0.0~b3~git2020032415.9f9040257-0ubuntu2","2:17.0.0~b3~git2020041013.7bb6314e4-0ubuntu1","2:17.0.0-0ubuntu0.20.04.1","2:17.0.1-0ubuntu1","2:17.0.1-0ubuntu2","2:17.0.1-0ubuntu2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"keystone","binary_version":"2:17.0.1-0ubuntu2+esm1"},{"binary_version":"2:17.0.1-0ubuntu2+esm1","binary_name":"keystone-common"},{"binary_name":"python3-keystone","binary_version":"2:17.0.1-0ubuntu2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90460.json"}},{"package":{"name":"keystone","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/keystone?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:20.0.0-0ubuntu1","2:20.0.0+git2021120815.2ddf8f321-0ubuntu1","2:20.0.0+git2022011217.771c943ad-0ubuntu1","2:20.0.0+git2022030313.a3fc9e7c3-0ubuntu1","2:21.0.0-0ubuntu1","2:21.0.1-0ubuntu1","2:21.0.1-0ubuntu2","2:21.0.1-0ubuntu2.1","2:21.0.1-0ubuntu2.2","2:21.0.1-0ubuntu2.4"],"ecosystem_specific":{"binaries":[{"binary_name":"keystone","binary_version":"2:21.0.1-0ubuntu2.4"},{"binary_name":"keystone-common","binary_version":"2:21.0.1-0ubuntu2.4"},{"binary_name":"python3-keystone","binary_version":"2:21.0.1-0ubuntu2.4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90460.json"}},{"package":{"name":"keystone","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/keystone?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:24.0.0-0ubuntu1","2:24.0.0+git2024011916.adfa92b4-0ubuntu1","2:25.0.0~rc1-0ubuntu1","2:25.0.0-0ubuntu1","2:25.0.0-0ubuntu1.1","2:25.0.0-0ubuntu1.2","2:25.0.0-0ubuntu1.4"],"ecosystem_specific":{"binaries":[{"binary_name":"keystone","binary_version":"2:25.0.0-0ubuntu1.4"},{"binary_name":"keystone-common","binary_version":"2:25.0.0-0ubuntu1.4"},{"binary_name":"python3-keystone","binary_version":"2:25.0.0-0ubuntu1.4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90460.json"}},{"package":{"name":"keystone","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/keystone?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"v
