When saving Virtual Network Computing (VNC) console settings, the configured password is passed directly as a command-line argument to an underlying system utility. A local unprivileged attacker on a host that allows cross-user process inspection could read the exposed password from the process list while another user modifies settings. This credential disclosure can allow unauthorized access to the guest virtual machine's graphical console.\n\n## Affected\n\n- `cockpit-machines (all versions)`\n- `cockpit-machines (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nMitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · updated 2026-10-20 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-113496.json)","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":27.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
