CVE-2026-46606

HIGH Exploitation: PoC
7.8
CVSS 3.1
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.
