{"id":"DEBIAN-CVE-2026-40214","details":"In OpenStack Cyborg before 16.0.1, the Accelerator Request (ARQ) API does not enforce project ownership at any layer. The project_id column in the database is never populated (NULL for every ARQ), database queries have no project filtering, and policy checks are self-referential (the authorize_wsgi decorator compares the caller's project_id with itself rather than the target resource). Any authenticated non-admin user can complete various actions such as deleting ARQs bound to other projects' instances, aka cross-tenant denial of service.","modified":"2026-09-14T17:03:28.908790508Z","published":"2026-05-07T22:16:35.047Z","upstream":["CVE-2026-40214"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-40214"}],"affected":[{"package":{"name":"cyborg","ecosystem":"Debian:13","purl":"pkg:deb/debian/cyborg?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"14.0.0-3+deb13u1"}]}],"versions":["14.0.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40214.json"}},{"package":{"name":"cyborg","ecosystem":"Debian:14","purl":"pkg:deb/debian/cyborg?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.0.0+git+2026.04.26.b8edfa06f1-1"}]}],"versions":["14.0.0-3","15.0.0-1","15.0.0~rc1-1","15.0.0~rc1-2","15.0.0~rc1-3","16.0.0-1","16.0.0-2","16.0.0~rc1-1","16.0.0~rc1-2","16.0.0~rc2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40214.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"}]}
