{"id":"CVE-2019-19687","aliases":["GHSA-2j23-fwqm-mgwr","PYSEC-2019-29"],"url":"https://o3.security/vulnerability/CVE-2019-19687","summary":"OpenStack Keystone Credential Leakage","details":"OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any user with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope is false. Users with a role on a project are able to view any other users' credentials, which could (for example) leak sign-on information for Time-based One Time Passwords (TOTP). Deployments with enforce_scope set to false are affected. (There will be a slight performance impact for the list credentials API once this issue is fixed.)","published":"2019-12-09T18:15:09.827Z","modified":"2026-07-08T20:16:09.273506Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"keystone","fixedVersion":"15.0.1"},{"ecosystem":"PyPI","name":"keystone","fixedVersion":"16.0.1"}],"fix":{"url":"https://github.com/openstack/keystone/commit/17947516b0095c51da5cff94771247f2e7c44ee6","label":"openstack/keystone@1794751"},"references":[{"type":"WEB","url":"https://usn.ubuntu.com/4262-1/"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/12/11/8"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4358"},{"type":"ADVISORY","url":"https://security.openstack.org/ossa/OSSA-2019-006.html"},{"type":"FIX","url":"https://review.opendev.org/#/c/697355/"},{"type":"FIX","url":"https://review.opendev.org/#/c/697611/"},{"type":"FIX","url":"https://review.opendev.org/#/c/697731/"},{"type":"EVIDENCE","url":"https://bugs.launchpad.net/keystone/+bug/1855080"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-19687"},{"type":"WEB","url":"https://github.com/openstack/keystone/commit/17947516b0095c51da5cff94771247f2e7c44ee6"},{"type":"WEB","url":"https://github.com/openstack/keystone/commit/17c337dbdbfb9d548ad531c2ad0483c9bce5b98f"},{"type":"WEB","url":"https://github.com/openstack/keystone/commit/bd3f63787151183f4daa43578aa491856fefae5b"},{"type":"WEB","url":"https://usn.ubuntu.com/4262-1"},{"type":"WEB","url":"https://review.opendev.org/#/c/697731"},{"type":"WEB","url":"https://review.opendev.org/#/c/697611"},{"type":"WEB","url":"https://review.opendev.org/#/c/697355"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/keystone/PYSEC-2019-29.yaml"},{"type":"PACKAGE","url":"https://github.com/openstack/keystone"},{"type":"WEB","url":"https://git.openstack.org/cgit/openstack/keystone/commit/?id=bd3f63787151183f4daa43578aa491856fefae5b"},{"type":"WEB","url":"https://git.openstack.org/cgit/openstack/keystone/commit/?id=17c337dbdbfb9d548ad531c2ad0483c9bce5b98f"},{"type":"WEB","url":"https://git.openstack.org/cgit/openstack/keystone/commit/?id=17947516b0095c51da5cff94771247f2e7c44ee6"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1781470"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T20:16:09.273506Z"}}
