{"cve":"CVE-2026-46606","nvd":{"published":"2026-06-25T19:16:37.380","modified":"2026-10-25T22:10:00.150","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78"],"references":["https://github.com/nicolargo/glances/releases/tag/v4.5.5","https://github.com/nicolargo/glances/security/advisories/GHSA-v5r2-qh84-fjx5","https://github.com/nicolargo/glances/security/advisories/GHSA-v5r2-qh84-fjx5"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-46606","score":0.00212,"percentile":0.1142,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v5r2-qh84-fjx5","url":"https://osv.dev/vulnerability/GHSA-v5r2-qh84-fjx5","summary":"Glances is Vulnerable to Command Injection via KVM/QEMU VM Domain Names in glances/plugins/vms/engines/virsh.py","modified":"2026-07-21T15:00:43.491185089Z","packages":[{"ecosystem":"PyPI","name":"glances","purl":"pkg:pypi/glances","ranges":["<4.5.5"],"fixed":["4.5.5"]}]},{"id":"PYSEC-2026-2497","url":"https://osv.dev/vulnerability/PYSEC-2026-2497","summary":"Glances is Vulnerable to Command Injection via KVM/QEMU VM Domain Names in glances/plugins/vms/engines/virsh.py","modified":"2026-07-13T16:31:55.159152828Z","packages":[{"ecosystem":"PyPI","name":"glances","purl":"pkg:pypi/glances","ranges":["<4.5.5"],"fixed":["4.5.5"]}]}],"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).
