Vulnerability from fkie_nvd - Published: 2026-08-21 15:16 - Updated: 2026-10-15 19:10
Severity
9.9 (Critical) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
Incus is a system container and virtual machine manager. Prior to version 7.2.0, an arbitrary file write exists in the Incus client when a malicious image server returns a crafted `Incus-Image-Hash` header. This can lead to arbitrary command execution as root on the server. Version 7.2.0 patches the issue.
