AI-suggested

Until a fix is available, limit local process inspection capabilities to trusted users only and restrict access to the host system during VM installation workflows to mitigate credential exposure risk.

Description

A vulnerability in cockpit-machines allows a local attacker with process inspection capabilities to expose sensitive guest VM credentials during the VM installation workflow. The issue arises because the install_machine.py script passes credentials as JSON command-line arguments, which can be viewed by processes with appropriate host visibility. The exposure is limited to the active installation period and requires local access with process inspection rights.
