All setups using Nova Filter Scheduler are affected. Because of the regression described in Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10, a 15.x version after 15.0.8, or a 16.x version after 16.0.3.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":[],"references":["http://www.securityfocus.com/bid/101950","https://access.redhat.com/errata/RHSA-2018:0241","https://access.redhat.com/errata/RHSA-2018:0314","https://access.redhat.com/errata/RHSA-2018:0369","https://launchpad.net/bugs/1664931"],"products":["openstack:nova"],"source":"nvd","synced_at":"2026-10-19T20:47:01.408438353+00:00"},"epss":{"cve":"CVE-2017-16239","score":0.01421,"percentile":0.72855,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w2wf-cgwh-vpqg","url":"https://osv.dev/vulnerability/GHSA-w2wf-cgwh-vpqg","summary":"OpenStack Nova Filter Scheduler Bypass","modified":"2026-07-06T08:11:38.073499563Z","packages":[{"ecosystem":"PyPI","name":"nova","purl":"pkg:pypi/nova","ranges":[">=16.0.0 <16.0.3"],"fixed":["16.0.3"]},{"ecosystem":"PyPI","name":"nova","purl":"pkg:pypi/nova","ranges":[">=15.0.0 <15.0.8"],"fixed":["15.0.8"]},{"ecosystem":"PyPI","name":"nova","purl":"pkg:pypi/nova","ranges":[">=14.0.0 <14.0.10"],"fixed":["14.0.10"]}]},{"id":"PYSEC-2026-694","url":"https://osv.dev/vulnerability/PYSEC-2026-694","summary":"OpenStack Nova Filter Scheduler Bypass","modified":"2026-07-06T08:00:47.883144579Z","packages":[{"ecosystem":"PyPI","name":"nova","purl":"pkg:pypi/nova","ranges":[">=14.0.0 <14.0.10",">=15.0.0 <15.0.8",">=16.0.0 <16.0.3"],"fixed":["14.0.10","15.0.8","16.0.3"]}]}],"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).
