{"cve":"CVE-2020-12690","nvd":{"published":"2020-05-07T00:15:10.923","modified":"2026-06-17T02:52:08.467","status":"Modified","description":"An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The list of roles provided for an OAuth1 access token is silently ignored. Thus, when an access token is used to request a keystone token, the keystone token contains every role assignment the creator had for the project. This results in the provided keystone token having more role assignments than the creator intended, possibly giving unintended escalated access.","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-613"],"references":["http://www.openwall.com/lists/oss-security/2020/05/07/3","https://bugs.launchpad.net/keystone/+bug/1873290","https://lists.apache.org/thread.html/re237267da268c690df5e1c6ea6a38a7fc11617725e8049490f58a6fa%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/re4ffc55cd2f1b55a26e07c83b3c22c3fe4bae6054d000a57fb48d8c2%40%3Ccommits.druid.apache.org%3E","https://security.openstack.org/ossa/OSSA-2020-005.html"],"products":["openstack:keystone"],"source":"nvd","synced_at":"2026-10-19T21:04:18.695612450+00:00"},"epss":{"cve":"CVE-2020-12690","score":0.01896,"percentile":0.7963,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-6m8p-x4qw-gh5j","url":"https://osv.dev/vulnerability/GHSA-6m8p-x4qw-gh5j","summary":"Insufficient Session Expiration in OpenStack Keystone","modified":"2024-09-27T18:35:07.141200Z","packages":[{"ecosystem":"PyPI","name":"keystone","purl":"pkg:pypi/keystone","ranges":["<15.0.1"],"fixed":["15.0.1"]},{"ecosystem":"PyPI","name":"keystone","purl":"pkg:pypi/keystone","ranges":[">=16.0.0.0rc1 <16.0.0"],"fixed":["16.0.0"]}]},{"id":"PYSEC-2020-54","url":"https://osv.dev/vulnerability/PYSEC-2020-54","summary":"","modified":"2023-11-08T04:02:11.225655Z","packages":[{"ecosystem":"PyPI","name":"keystone","purl":"pkg:pypi/keystone","ranges":["<15.0.1"],"fixed":["15.0.1"]}]}],"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).
