NVD Description

Note: Versions mentioned in the description apply only to the upstream cockpit-machines package and not the cockpit-machines package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in cockpit-machines. This vulnerability allows a local attacker with the ability to inspect running processes to expose sensitive guest virtual machine (VM) credentials, such as rootPassword and userPassword. This occurs when the install_machine.py script passes these credentials as a JSON command-line argument during VM creation or installation. The exposure is limited to the period when the installation workflow is active and depends on host process-visibility policies.
