Hi,

The following vulnerability was published for cockpit-machines.

CVE-2026-113496[0]:
| A flaw was found in cockpit-machines. 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
