{"id":"CVE-2026-46606","summary":"Glances: Command Injection via KVM/QEMU VM Domain Names in glances/plugins/vms/engines/virsh.py","details":"Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances KVM/QEMU monitoring engine (glances/plugins/vms/engines/virsh.py) passes VM domain names, read directly from virsh list --all output, into f-string command templates that are processed by secure_popen(). secure_popen() is explicitly designed to interpret &&, |, and \u003e as shell operators. Because domain names are never sanitised before interpolation, any user with the ability to create or rename a KVM/QEMU virtual machine can execute arbitrary commands as the OS user running Glances — commonly root on hypervisor hosts. This vulnerability is fixed in 4.5.5.","aliases":["GHSA-v5r2-qh84-fjx5"],"modified":"2026-06-26T18:29:25.148488995Z","published":"2026-06-25T18:02:14.168Z","related":["openSUSE-SU-2026:11122-1"],"database_specific":{"cwe_ids":["CWE-78"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46606.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46606.json"},{"type":"WEB","url":"https://github.com/nicolargo/glances/releases/tag/v4.5.5"},{"type":"ADVISORY","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-v5r2-qh84-fjx5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46606"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nicolargo/glances","events":[{"introduced":"0"},{"fixed":"988cad68474509557aa2db75f928393c00226979"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"4.5.5"}]}}],"versions":["v4.5.4","v4.5.3","v4.5.2","v4.5.1","v4.5.0.5","v4.5.0.4","v4.5.0.3","v4.5.0.2","v4.5.0.1","v4.5.0","v4.4.1","v4.4.0","v4.3.3","v4.3.2","v4.3.1","v4.3.0.8","v4.3.0.7","v4.3.0.6","v4.3.0.3","v4.3.0.2","v4.3.0.1","v4.3.0","v4.2.0","v3.4.0","v3.3.1","v3.3.0.1","v3.3.0","v3.2.7","v3.2.6","v3.2.5","v3.2.4.2","v3.2.4.1","v3.2.4","v3.2.3.1","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.7","v3.1.6.1","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0","v2.11","v2.10","v2.9.1","v2.9.0","v2.8.8","v2.8.7","v2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8","v2.7.1","v2.7","v2.7_RC1","v2.5.1","v2.5","v2.4.2","v2.4.1","v2.3","v2.2","v1.7.3","v1.7.2","v1.7.1","v1.7","v1.6.1","v1.6","v1.5.2","v1.5.1","v1.5","v1.4.2.1","v1.4.2","v1.4.1.1","v1.4.1","v1.4","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3","v1.2","v1.1.3","v1.1.2","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46606.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
