glances: Glances is an open-source system cross-platform monitoring tool
CVE-2026-46606 is fixed in glances on 1 platform by DEBIAN-CVE-2026-46606 (version 4.5.5+dfsg-1), released June 26, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
