CVE-2026-92747
Cockpit-machines: cockpit-machines: sensitive data exposure of guest credentials via json argument in process list
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.
