{"id":"CVE-2026-46606","aliases":["GHSA-v5r2-qh84-fjx5","PYSEC-2026-2497"],"url":"https://o3.security/vulnerability/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 > 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.","published":"2026-06-25T18:02:14.168Z","modified":"2026-08-12T03:51:13.460914944Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00142,"percentile":0.04003,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"glances","fixedVersion":"4.5.5"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/nicolargo/glances/releases/tag/v4.5.5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46606.json"},{"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.460914944Z"}}
