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.)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-522"],"references":["http://www.openwall.com/lists/oss-security/2019/12/11/8","https://access.redhat.com/errata/RHSA-2019:4358","https://bugs.launchpad.net/keystone/+bug/1855080","https://review.opendev.org/#/c/697355/","https://review.opendev.org/#/c/697611/"],"products":["openstack:keystone"],"source":"nvd","synced_at":"2026-10-19T20:59:27.069234358+00:00"},"epss":{"cve":"CVE-2019-19687","score":0.0178,"percentile":0.78254,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2j23-fwqm-mgwr","url":"https://osv.dev/vulnerability/GHSA-2j23-fwqm-mgwr","summary":"OpenStack Keystone Credential Leakage","modified":"2024-09-27T20:36:29Z","packages":[{"ecosystem":"PyPI","name":"keystone","purl":"pkg:pypi/keystone","ranges":[">=15.0.0 <15.0.1"],"fixed":["15.0.1"]},{"ecosystem":"PyPI","name":"keystone","purl":"pkg:pypi/keystone","ranges":[">=16.0.0 <16.0.1"],"fixed":["16.0.1"]}]},{"id":"PYSEC-2019-29","url":"https://osv.dev/vulnerability/PYSEC-2019-29","summary":"","modified":"2026-06-10T17:01:58.389944091Z","packages":[{"ecosystem":"PyPI","name":"keystone","purl":"pkg:pypi/keystone","ranges":["<16.0.1"],"fixed":["16.0.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
