Hi,

The following vulnerability was published for cockpit-machines.

CVE-2026-113495[0]:
| A flaw was found in cockpit-machines. Red Hat Subscription
| Management (RHSM) authentication tokens are passed as command-line
| arguments to background helper processes during image retrieval
| operations. A local, unprivileged attacker on a system permitting
| cross-user process inspection can view these arguments while the
| process is active. This flaw can lead to information disclosure,
| potentially allowing unauthorized access to RHSM resources within
| the token's validity period.


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