{"id":"CVE-2019-19687","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.)","aliases":["GHSA-2j23-fwqm-mgwr","PYSEC-2019-29"],"modified":"2026-04-10T04:16:53.957089Z","published":"2019-12-09T18:15:09.827Z","references":[{"type":"WEB","url":"https://usn.ubuntu.com/4262-1/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:4358"},{"type":"ADVISORY","url":"https://security.openstack.org/ossa/OSSA-2019-006.html"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/12/11/8"},{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openstack/keystone","events":[{"introduced":"0"},{"last_affected":"c78581b4608f3dc10e945d358963000f284f188a"},{"introduced":"0"},{"last_affected":"dc9e9e32dfbf9fd9c58f9f8e2b35f0bcfd62328e"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"15.0.0"},{"introduced":"0"},{"last_affected":"16.0.0"}]}}],"versions":["10.0.0.0b1","10.0.0.0b2","10.0.0.0b3","10.0.0.0rc1","11.0.0","11.0.0.0b1","11.0.0.0b2","11.0.0.0b3","11.0.0.0rc1","12.0.0.0b1","12.0.0.0b2","12.0.0.0b3","12.0.0.0rc1","13.0.0.0b1","13.0.0.0b2","13.0.0.0b3","13.0.0.0rc1","14.0.0.0b1","14.0.0.0b2","14.0.0.0rc1","15.0.0","15.0.0.0rc1","15.0.0.0rc2","16.0.0","16.0.0.0rc1","16.0.0.0rc2","2011.3","2013.2.b1","2013.2.b3","2013.2.rc1","2014.1.b1","2014.1.b2","2014.1.b3","2014.1.rc1","2014.2.b1","2014.2.b2","2014.2.b3","2014.2.rc1","2015.1.0b1","2015.1.0b2","2015.1.0b3","2015.1.0rc1","8.0.0.0b1","8.0.0.0b2","8.0.0.0b3","8.0.0.0rc1","8.0.0a0","9.0.0.0b1","9.0.0.0b2","9.0.0.0b3","9.0.0.0rc1","essex-4","essex-rc1","folsom-1","folsom-2","folsom-rc1","grizzly-1","grizzly-2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-19687.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
