{"id":"PYSEC-2026-1708","summary":"OpenStack Cinder, Glance, and Nova vulnerable to arbitrary file access","details":"An issue was discovered in OpenStack Cinder through 24.0.0, Glance before 28.0.2, and Nova before 29.0.3. Arbitrary file access can occur via custom QCOW2 external data. By supplying a crafted QCOW2 image that references a specific data file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data. All Cinder and Nova deployments are affected; only Glance deployments with image conversion enabled are affected.","aliases":["CVE-2024-32498","GHSA-r4v4-w9pv-6fph","PYSEC-2026-2414","PYSEC-2026-2493"],"modified":"2026-07-13T16:43:17.725861996Z","published":"2026-07-07T14:34:36.285308Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-32498"},{"type":"WEB","url":"https://github.com/openstack/cinder/commit/78f85c1f9b20a067ef64d6451dee0228c3a0db5e"},{"type":"WEB","url":"https://github.com/openstack/cinder/commit/d6a186945e03649343af55b46ed8dfe0dd326e40"},{"type":"WEB","url":"https://github.com/openstack/glance/commit/22f0c9c6f98db1d93569e3edb800c271f35b0ef9"},{"type":"WEB","url":"https://github.com/openstack/glance/commit/2e65391744a82421bc6f026ee8f1f3550038f175"},{"type":"WEB","url":"https://github.com/openstack/glance/commit/867d1dd8b6e4f5774257a98c7c33061fbbbde973"},{"type":"WEB","url":"https://github.com/openstack/glance/commit/cc7d53adbecf85f3d7df78e7618fe8ab3a075c5f"},{"type":"WEB","url":"https://github.com/openstack/glance/commit/d607e78630cc9d1ca18b3a027322809c042f64df"},{"type":"WEB","url":"https://github.com/openstack/nova/commit/657e86585cc57f84ab9b364dd189547d231d5927"},{"type":"WEB","url":"https://launchpad.net/bugs/2059809"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00016.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00017.html"},{"type":"WEB","url":"https://security.openstack.org/ossa/OSSA-2024-001.html"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2024/07/02/2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/07/02/2"},{"type":"PACKAGE","url":"https://pypi.org/project/nova"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-r4v4-w9pv-6fph"}],"affected":[{"package":{"name":"nova","ecosystem":"PyPI","purl":"pkg:pypi/nova"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"29.0.2"}]}],"versions":["15.1.5","16.1.6","16.1.7","16.1.8","17.0.10","17.0.11","17.0.12","17.0.13","17.0.7","17.0.8","17.0.9","18.0.2","18.0.3","18.1.0","18.2.0","18.2.1","18.2.2","18.2.3","18.3.0","19.0.0","19.0.0.0rc1","19.0.0.0rc2","19.0.1","19.0.2","19.0.3","19.1.0","19.2.0","19.3.0","19.3.1","19.3.2","20.0.0","20.0.0.0rc1","20.0.0.0rc2","20.0.1","20.1.0","20.1.1","20.2.0","20.3.0","20.4.0","20.4.1","20.5.0","20.6.0","20.6.1","21.0.0","21.0.0.0rc1","21.0.0.0rc2","21.1.0","21.1.1","21.1.2","21.2.0","21.2.1","21.2.2","21.2.3","21.2.4","22.0.0","22.0.0.0rc1","22.0.1","22.1.0","22.2.0","22.2.1","22.2.2","22.3.0","22.4.0","23.0.0","23.0.0.0rc1","23.0.0.0rc2","23.0.1","23.0.2","23.1.0","23.2.0","23.2.1","23.2.2","24.0.0","24.0.0.0rc1","24.0.0.0rc2","24.1.0","24.1.1","24.2.0","24.2.1","25.0.0","25.0.0.0rc1","25.0.1","25.1.0","25.1.1","25.2.0","25.2.1","25.3.0","26.0.0","26.0.0.0rc1","26.0.0.0rc2","26.1.0","26.1.1","26.2.0","26.2.1","26.2.2","26.3.0","27.0.0","27.0.0.0rc1","27.1.0","27.2.0","27.3.0","27.4.0","27.5.0","27.5.1","28.0.0","28.0.0.0rc1","28.0.1","28.1.0","28.2.0","28.3.0","28.3.1","29.0.0","29.0.0.0rc1","29.0.1","29.0.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/nova/PYSEC-2026-1708.yaml"}}],"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:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
